Coly Li 02a4b14d17 bcache: avoid NULL checking to c->root in run_cache_set() 
[ Upstream commit 3eba5e0b24 ]

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.
