p54: Initialize extra_len in p54_tx_80211
This patch fixes a very serious off-by-one bug in
the driver, which could leave the device in an
unresponsive state.
The problem was that the extra_len variable [used to
reserve extra scratch buffer space for the firmware]
was left uninitialized. Because p54_assign_address
later needs the value to reserve additional space,
the resulting frame could be to big for the small
device's memory window and everything would
immediately come to a grinding halt.
