Namjae Jeon 795cea4731 ksmbd: fix stream write failure 
[ Upstream commit 1f4bbedd4e ]

If there is no stream data in file, v_len is zero.
So, If position(*pos) is zero, stream write will fail
due to stream write position validation check.
This patch reorganize stream write position validation.

Fixes: 0ca6df4f40 ("ksmbd: prevent out-of-bounds stream writes by validating *pos")
