In the error path for efa_com_alloc_comp_ctx() the semaphore assigned to
&aq->avail_cmds is not released.

Detected by Smatch:
drivers/infiniband/hw/efa/efa_com.c:662 efa_com_cmd_exec() warn:
inconsistent returns '&aq->avail_cmds'

Add release for &aq->avail_cmds in efa_com_alloc_comp_ctx() error path.
