[PATCH 2/2] char: fix possible double-unlock in specialix.c

[Harvey Harrison]

Noticed by sparse, trivial to see:
drivers/char/specialix.c:2112:3: warning: context imbalance in 'sx_throttle' - unexpected unlock

Signed-off-by: Harvey Harrison <harvey.harrison@xxxxxxxxx>

And with the torrent of warnings fixed, here we find a double-unlock.
