Description of problem:
I've installed system in fips mode and after installed system booted, I've removed first byte in hmac file for vmlinuz in /boot. After reboot, dracut drops to dracut shell stating "Warning: dracut: Refusing to continue". I've pressed ctrl-d, dracut again drops to shell, pressed ctrl-d and then boot continued into system.

Version-Release number of selected component (if applicable):
dracut-033-68.el7
RHEL-7.0-20140110.0 x86_64 Client

How reproducible:
always

Steps to Reproduce:
1. Install system with fips enabled
2. In installed system, remove first byte from file /boot/.vmlinuz-3.10.0-67.el7.x86_64.hmac
3. reboot
4. once dropped in dracut shell, press ctrl-d
5. once dropped in dracut shell, press ctrl-d

Actual results:
System boots (although some strange issues happen, e.g. /boot is not mounted)

Expected results:
One shouldn't be dropped to dracut shell and system doesn't boot.
