scsi: mpi3mr: Fix cmnd getting marked as in use forever

BugLink: https://bugs.launchpad.net/bugs/1967116
When a driver command which requires the driver to issue a follow up
command using the same command frame is outstanding and a soft reset
operation occurs, then that driver command frame is getting marked as in
use permanently and won't be reused again.

Clear the driver command frames while flushing out the outstanding commands
and avoid issuing any new requests using these command frames while soft
reset is going on.
