Btrfs devel - Nov 2010 - [PATCH] kmem_cache_alloc doesn't return ERR_PTR so no need to check for it.

According to scripts/coccinelle/null/eno.cocci "The various basic
memory allocation functions don''t return ERR_PTR" so
there''s no
point in calling IS_ERR() on the return value from them, the
existing test is good enough.
