btrfs: reduce block group critical section in pin_down_extent()

There's no need to update the bytes_reserved and bytes_may_use fields of
the space_info while holding the block group's spinlock. We are only
making the critical section longer than necessary. So move the space_info
updates outside of the block group's critical section.
