cifs: Fix copy_to_iter return value check
The return value of copy_to_iter() function will never be negative,
it is the number of bytes copied, or zero if nothing was copied.
Update the check to treat 0 as an error, and return -1 in that case.
Fixes: d08089f649a0 ("cifs: Change the I/O paths to use an iterator rather than a page list")
