Yuezhang Mo c4034574f8 exfat: fix remount failure in different process environments 
[ Upstream commit 51fc7b4ce1 ]

The kernel test robot reported that the exFAT remount operation
failed. The reason for the failure was that the process's umask
is different between mount and remount, causing fs_fmask and
fs_dmask are changed.

Potentially, both gid and uid may also be changed. Therefore, when
initializing fs_context for remount, inherit these mount options
from the options used during mount.
