[PATCH net-next 03/16] net: pcs: xpcs: Return EINVAL in the internal methods

In particular the xpcs_soft_reset() and xpcs_do_config() functions
currently return -1 if invalid auto-negotiation mode is specified. That
value can be then passed to the generic kernel subsystems which require a
standard kernel errno value. Even though the error conditions are very
specific (memory corruption or buggy implementation) using a hard-coded -1
literal doesn't seem correct anyway.
