[PATCH] staging: wfx: Fix a memory leak in 'wfx_upload_beacon'

[Christophe JAILLET]

The current code is a no-op, because all it can do is 'dev_kfree_skb(NULL)'
Revert the test to free skb, if not NULL.

This patch is purely speculative.

The 'if  (...)' could also be removed completely if we refactor the code
and return directly at the beginning of the function.
Or the 'return -ENOMEM' should be 'err = -ENOMEM; goto done;' in order to
avoid a mixup of goto and direct return.
