ksmbd: fix SMB 3.11 posix extension mount failure
commit 9ca8581e79e51c57e60b3b8e3b89d816448f49fe upstream.
cifs client set 4 to DataLength of create_posix context, which mean
Mode variable of create_posix context is only available. So buffer
validation of ksmbd should check only the size of Mode except for
the size of Reserved variable.
Fixes: 8f77150c15f8 ("ksmbd: add buffer validation for SMB2_CREATE_CONTEXT")
