From: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx>
for EDMA based chipsets there are few more errors/invalid conditions to
be handled when processing tx descriptors apart from descriptor
processing incomplete.
based on the commit dcfcbd590d91e8385eb554aaed419bdebaf4c72a
ENOENT error happened in ad-hoc mode during the invocation of
drv_last_beacon
