ksmbd_file_table_flush is a leftover from SMB1. This function is no longer
needed as SMB1 has been removed from ksmbd.

Append ksmbd_lock into the connection's
lock list and the ksmbd_file's lock list.
And when a file is closed, detach ksmbd_lock
from these lists and free it.

This patch change data type of volatile/persistent id to u64 to make
issue from idr_find and idr_remove(). !HAS_FILE_ID check will protect

For user namespace support, call vfs functions
with struct user_namespace got from struct path.
This patch have been tested mannually as below.
Create an id-mapped mount using the mount-idmapped utility
(https://github.com/brauner/mount-idmapped).
$ mount-idmapped --map-mount b:1003:1002:1 /home/foo <EXPORT DIR>/foo
(the user, "foo" is 1003, and the user "bar" is 1002).
And mount the export directory using cifs with the user, "bar".
succeed to create/delete/stat/read/write files and directory in
the <EXPORT DIR>/foo. But fail with a bind mount for /home/foo.
