Btrfs: remove lock assert from get_restripe_target()
This fixes a regression introduced by fc67c450. spin_is_locked() always returns 0 on UP kernels, which caused assert in get_restripe_target() to be fired on every call from btrfs_reduce_alloc_profile() on UP systems. Remove it completely for now, it's not clear if it's going to be needed in future.
