A prior commit included a udev check for MPATH_DEVICE_READY to
determine if a path was multipath when doing an autoreplace:
f2f6c18 zed: Misc multipath autoreplace fixes
However, MPATH_DEVICE_READY is not provided by the older version of
udev that's on Centos 7 (it is on Centos 8).
This patch instead looks for 'mpath-' in the UUID, which works on
both Centos 7 and 8.

Motivation and Context
Fix multipath autoreplace on Centos 7
Description
A prior commit included a udev check for MPATH_DEVICE_READY to determine if a path was multipath when doing an autoreplace:
f2f6c18 zed: Misc multipath autoreplace fixes
However, MPATH_DEVICE_READY is not provided udev on Centos 7 (but is on Centos 8).
This patch instead looks for 'mpath-' in the UUID, which works on both Centos 7 and 8.
How Has This Been Tested?
Tested autoreplace with a JBOD on both Centos 7 and Centos 8. Saw that old code didn't autoreaplace on Centos 7, and then saw it working with this PR. Also tested autoreplace with an additional JBOD type on Centos 8.
