greybus: use PTR_ERR_OR_ZERO()
Coccinelle points out that the macro PTR_ERR_OR_ZERO() handles the
frequent case of converting a pointer into either error code (if its
value is an encoded error value) or 0 (otherwise). Switch some code
in gb_power_supply_register() to use that macro. I have verified
this is true of the kernel we're now working with (arche-6.0).
