btrfs: fix build warning
We were getting build warning about: fs/btrfs/extent-tree.c:7021:34: warning: ‘used_bg’ may be used uninitialized in this function It is not a valid warning as used_bg is never used uninitilized since locked is initially false so we can never be in the section where 'used_bg' is used. But gcc is not able to understand that and we can initialize it while declaring to silence the warning.
