ksmbd: fix stream write failure
[ Upstream commit 1f4bbedd4e5a69b01cde2cc21d01151ab2d0884f ]
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: 0ca6df4f40cf ("ksmbd: prevent out-of-bounds stream writes by validating *pos")
