btrfs: switch to refcount_t type for btrfs_trans_handle::use_count
The use_count is a reference counter, we can use the refcount_t type, though we don't use the atomicity. This is not a performance critical code and we could catch the underflows. The type is changed from long, but the number of references will fit an int. Signed-off-by: David Sterba <dsterba@suse.com>
