Subject: [PATCH] librbd/cache/pwl/ssd: ensure bdev and pool sizes match

m_log_pool_size should be multiple of 1M but, just in case, prevent
is_valid_io() assert in KernelDevice::aio_write().

Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
(cherry picked from commit 41b95ac987954dc2c29090926236660b8348e9d2)
