HID: i2c-hid: Switch i2c_hid_parse() to goto style error handling

Switch i2c_hid_parse() to goto style error handling.

This is a preparation patch for removing the need for
I2C_HID_QUIRK_NO_IRQ_AFTER_RESET by making i2c-hid behave
more like Windows.

Note this changes the descriptor read error path to propagate
the actual i2c_hid_read_register() error code (which is always
negative) instead of hardcoding a -EIO return.
