ceph: wait for async creating inode before requesting new max size

Browse source 
ceph_check_caps() can't request new max size for async creating inode.
This may make ceph_get_caps() loop busily until getting reply of the
async create. Also, wait for async creating reply before calling
ceph_renew_caps().
