btrfs: remove useless used space increment during space reservation 



At space-info.c:__reserve_bytes(), we increment the 'used' variable, but
then we don't use the variable anymore, making the increment pointless.
The increment became useless with commit 2e294c60 ("btrfs: simplify
the logic in need_preemptive_flushing"), so just remove it.
