staging: gpib: use int type to store negative error codes

The "ret" variable is used to store the return from bb_write() returns
either zero on success or negative error codes on failure.  Storing the
error codes in size_t which is an unsigned long, doesn't cause an issue
at runtime but it's ugly as pants.  Change "ret" from size_t to int
type.  No effect on runtime.
