H A Ddm-cache-policy-smq.cdiff 134bf30c06f057d6b8d90132e8f8b3cd2be79572 Thu Jul 23 10:47:59 CDT 2015 Colin Ian King <colin.king@canonical.com> dm cache policy smq: fix alloc_bitset check that always evaluates as false

static analysis by cppcheck has found a check on alloc_bitset that
always evaluates as false and hence never finds an allocation failure:

[drivers/md/dm-cache-policy-smq.c:1689]: (warning) Logical conjunction
always evaluates to false: !EXPR && EXPR.

Fix this by removing the incorrect mq->cache_hit_bits check
