rt2x00: rt2800lib: use rt2x00dev->bcn->winfo_size 

The beacon data queue is initialized already when
the rt2800_clear_beacon_register() function is called.

Fetch the size of the TXWI descriptor from that
instead of using the winfo_size field of the data
queue descriptor.

The two values are the same, and the use of the
rt2x00dev->bcn->winfo_size value allows us to
get rid of a superfluous pointer dereference.
