Revert "mwifiex: fix sleep in atomic context bugs caused by dev_coredumpv"

commit f8043a20f8e127b1cdd34386c3285c5e00e3fbe8 upstream.

This reverts commit b1ac17142ca2cd45458d4385559d9d3ce3987150 as it
causes build problems in linux-next.  It needs to be reintroduced in a
way that can allow the api to evolve and not require a "flag day" to
catch all users.
