wifi: wfx: Fix error handling in wfx_core_init()

Browse Source 
[ Upstream commit 3b88a9876779b55478a4dde867e73f7a100ffa23 ]

The wfx_core_init() returns without checking the retval from
sdio_register_driver().
If the sdio_register_driver() failed, the module failed to install,
leaving the wfx_spi_driver not unregistered.

Fixes: a7a91ca5a2 ("staging: wfx: add infrastructure for new driver")
