Tomas Henzl 0d4a00b23a scsi: megaraid_sas: Fix for a potential deadlock 
[ Upstream commit 50740f4dc78b41dec7c8e39772619d5ba841ddd7 ]

This fixes a 'possible circular locking dependency detected' warning
      CPU0                    CPU1
      ----                    ----
 lock(&instance->reset_mutex);
                              lock(&shost->scan_mutex);
                              lock(&instance->reset_mutex);
 lock(&shost->scan_mutex);

Fix this by temporarily releasing the reset_mutex.
