b43: Fix unload oops if firmware is not available
The asyncronous firmware load uses a completion struct to hold firmware
processing until the user-space routines are up and running. There is.
however, a problem in that the waiter is nevered canceled during teardown.
As a result, unloading the driver when firmware is not available causes an oops.
To be able to access the completion structure at teardown, it had to be moved
into the b43_wldev structure.
This patch also fixes a typo in a comment.
