common: do not release lock after nvmem read when commits are suspended
The nvmem_release_cache() function checks if there is a pending write
and refuses to release the lock if so. It should also be checking if
submits have need suspended, as the task suspending commits is holding
the lock and is supposed to release it explicitly when done.
BRANCH=none
BUG=chrome-os-partner:62531
TEST=verified that the message reporting attempts to commit when cache
is unlocked is not showing up at startup any more,
