[ Upstream commit 087d764159996ae378b08c0fdd557537adfd6899 ]

In the resume stage of GPU recovery, start_cpsch will call pm_init which set pm->allocated as false, cause the next pm_release_ib has no chance to release ib memory.

Add pm_release_ib in stop_cpsch which will be called in the suspend stage of GPU recovery.
