Add checks for the return value of alloc_workqueue and
alloc_ordered_workqueue as they may return NULL pointer and cause NULL
pointer dereference.
Moreover, destroy them when fails later in order to avoid memory leak.

This works just fine for modes today.
I assume this is this need to have userspace also check for position
info
Add check for the return value of alloc_ordered_workqueue as it may return
NULL pointer.
Moreover, use the destroy_workqueue in the later fails in order to avoid
memory leak.
