bnge: use int for bnge_fix_rings_count() return value

bnge_fix_rings_count() returns 0 on success or a negative errno on failure
However, bnge_adjust_rings() stores its return value in a u16 variable,
causing negative error codes such as -ENOMEM to be converted to a large
positive value.

Use an int for the return code variable so that error values are
preserved and propagated correctly.
