Kamal Heib 8dacf7a5ab RDMA/hfi1: Fix memory leak in _dev_comp_vect_mappings_create
commit 8a4f300b97 upstream.

Make sure to free the allocated cpumask_var_t's to avoid the following
reported memory leak by kmemleak:

$ cat /sys/kernel/debug/kmemleak
unreferenced object 0xffff8897f812d6a8 (size 8):
  comm "kworker/1:1", pid 347, jiffies 4294751400 (age 101.703s)
  hex dump (first 8 bytes):
    00 00 00 00 00 00 00 00                          ........
