btrfs: fix uninitialized variable warning in btrfs_update_block_group

[ Upstream commit efbf35a102b20246cfe4409c6ae92e72ecb67ab8 ]

reclaim isn't set in the alloc case, however we only care about
reclaim in the !alloc case.  This isn't an actual problem, however
-Wmaybe-uninitialized will complain, so initialize reclaim to quiet the
compiler.
