Patch to add MAXCONCURRENT variable to raid-check none

Patch to add MAXCONCURRENT

Description of problem:

I've got some disk servers with 4 9TB radi5 arrays.  raid-check puts too much
of a load on them.  The attached patch (to mdadm-3.2.2-9) allows the use of a
MAXCONCURENT option that limits the number of concurrently checked arrays.

This is a quick port of the EL5 version.  Will test it out this weekend.

Version-Release number of selected component (if applicable):
mdadm-3.2.2-9
