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.

For user namespace support, we need to pass
struct user_namespace with struct dentry
to some functions. For reducing the number
of arguments, replace the struct dentry with
struct path in these functions.

smb2_validate_credit_charge() checks the CreditCharge field in the
request is valid with regards to the payload size.
The current implementation rejects requests with CreditCharge = 0 and a
payload < 64K, even though they should be accepted.
Set CreditCharge to a minimum value of 1 to avoid rejecting such
requests. This matches what samba4 does.
