ceph: apply nearfull_sync option on remount
ceph_parse_mount_param() stores nearfull_sync / nonearfull_sync on the
temporary fs_context options, but ceph_reconfigure_fc() never copied
CEPH_MOUNT_OPT_NEARFULL_SYNC onto the live mount. Remount therefore
succeeded while writes and /proc/mounts kept the original-mount flag.
Apply the flag the same way as ASYNC_DIROPS and SPARSEREAD so remount
can enable or disable NEARFULL IOCB_DSYNC promotion.
Fixes: c7a12c20bfba ("ceph: make nearfull sync writes opt-in")
