[PATCH 2/5] mac80211: Initialize sta pointer

[Ivo van Doorn <ivdoorn@gmail.com>]

patch: mac80211: rewrite fragmentation code
introduced the following compile warning:

net/mac80211/tx.c: In function 'ieee80211_master_start_xmit':
net/mac80211/tx.c:1244: warning: 'sta' may be used uninitialized in this function

sta is allowed to be NULL throughout the rest of the function,
so we best initialize it to NULL.
