Subject: [PATCH 1/1] mpt3sas: Fix - Remove cpumask_clear for zalloc_cpumask_var and dont free free_cpu_mask_var before reply_q

From: Suganath prabu Subramani <suganath-prabu.subramani@...adcom.com>

Removed cpumask_clear as it is not required for zalloc_cpumask_var and
free free_cpumask_var before freeing reply_q.
