[ Upstream commit 3eba5e0b2422aec3c9e79822029599961fdcab97 ]
In run_cache_set() after c->root returned from bch_btree_node_get(), it is checked by IS_ERR_OR_NULL(). Indeed it is unncessary to check NULL because bch_btree_node_get() will not return NULL pointer to caller.
This patch replaces IS_ERR_OR_NULL() by IS_ERR() for the above reason.
