Description of problem:
lvm2-lvmpolld.socket is set to forcibly enable in the RPM --scripts for lvm2. However the Red Hat provided systemd preset policy (redhat-release-server) does not match this enforced state (/usr/lib/systemd/system-preset/90-default.preset)

Version-Release number of selected component (if applicable):
redhat-release-server-7.2-9.el7.x86_64
lvm2-2.02.130-5.el7_2.1.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1. sudo systemctl status lvm2-lvmpolld.socket

Actual results:
● lvm2-lvmpolld.socket - LVM2 poll daemon socket
   Loaded: loaded (/usr/lib/systemd/system/lvm2-lvmpolld.socket; enabled; vendor preset: disabled)
   Active: active (listening) since Wed 2016-03-09 15:56:51 AEDT; 17h ago
     Docs: man:lvmpolld(8)
   Listen: /run/lvm/lvmpolld.socket (Stream)


Expected results:
● lvm2-lvmpolld.socket - LVM2 poll daemon socket
   Loaded: loaded (/usr/lib/systemd/system/lvm2-lvmpolld.socket; enabled; vendor preset: enabled)
   Active: active (listening) since Wed 2016-03-09 15:56:51 AEDT; 17h ago
     Docs: man:lvmpolld(8)
   Listen: /run/lvm/lvmpolld.socket (Stream)


Additional info:
rpm -q --scripts lvm2
....
if [ $1 -eq 1 ] ; then 
        # Initial installation 
        systemctl preset lvm2-lvmpolld.socket >/dev/null 2>&1 || : 
fi 

# lvm2-lvmpolld socket is always enabled and started and ready to serve if lvmpolld is used
# replace direct systemctl calls with systemd rpm macro once this is provided in the macro:
# http://cgit.freedesktop.org/systemd/systemd/commit/?id=57ab2eabb8f92fad5239c7d4492e9c6e23ee0678
systemctl enable lvm2-lvmpolld.socket
systemctl start lvm2-lvmpolld.socket
....

We can work around this by placing in our own preset policy to enable it in /etc/systemd/system-preset/, but Redhat should already provide this policy if it is the default or only use systemctl preset in the RPM.
