e1000e: Validate hwtstamp_config completely before applying it

Browse source

e1000e_hwtstamp_ioctl() should validate all fields of hwtstamp_config
before making any changes.  Currently it copies the configuration to
the e1000_adapter structure before validating it at all.

Change e1000e_config_hwtstamp() to take a pointer to the
hwstamp_config and to copy the config after validating it.

Compile-tested only.
