[PATCH v2] mwifiex: handle error if IRQ request fails in mwifiex_sdio_of()

[Amitkumar Karwar]

When this failure occurs, we will clear card->plt_wake_cfg so that
device would initialize without wake up on external interrupt feature.
This feature specific code in suspend and resume handlers will be
skipped.

We were returning error in this failure case in v1 patch from Javier
Martinez Canillas. In v2, we allow device to initialize successfully.
