From: Vladimir Kondratiev <qca_vkondrat@xxxxxxxxxxxxxxxx>
When resetting target in wil_target_reset(), error may occur.
Indicate error via error code. In case of error, don't attempt to further
interact with card, specifically don't attempt firmware download or
interrupts enabling.
Move wil_rx_fini() to be always executed to prevent memory leak.
