[PATCH] scsi: smartpqi silence a recursive lock warning

[Tomas Henzl <thenzl@redhat.com>]

On systems with multiple controllers debug kernel shows 
WARNING: possible recursive locking detected 
during shutdown.
Each controller does have its own ctrl_info (and mutex)
and that isn't correctly recognized by debug kernel.
Supress the warning by releasing the mutex at the end of pqi_shutdown.
