[PATCH v2 5/5] mwifiex: wait firmware dump complete during card remove process

[Amitkumar Karwar <akarwar@marvell.com>]

From: Xinming Hu <huxm@marvell.com>

Wait for firmware dump complete in card remove function.
For sdio interface, there are two diffenrent cases,
card reset trigger sdio_work and firmware dump trigger sdio_work.
Do code rearrangement for distinguish between these two cases.

v2: 1. Get rid of reset_triggered flag. Instead split the code and use
    __mwifiex_sdio_remove() (Brian Norris/Dmitry Torokhov)
    2. "v1 4/5 mwifiex: firmware dump code rearrangement.." is dropped. So
    rebased accordingly.
