mac80211: Remove unused 'struct rate_control_ref' variable

Commit 3b17fbf87d5d introduced sta_get_expected_throughput()
leaving variable 'struct rate_control_ref* ref' set but unused.
Compiling with W=1 gives the following warning, fix it.

net/mac80211/sta_info.c: In function ‘sta_set_sinfo’:
net/mac80211/sta_info.c:2052:27: warning: variable ‘ref’ set but not used [-Wunused-but-set-variable]

Fixes: 3b17fbf87d5d ("mac80211: mesh: Add support for HW RC implementation")
