[PATCH 35/40] [SRU][Lunar/OEM-6.1] wifi: rtw89: phy: add dummy C2H handler to avoid warning message

[Koba Ko]

From: Ping-Ke Shih <pkshih at realtek.com>

BugLink: https://bugs.launchpad.net/bugs/2002601

The C2H class 2 function 3 is to report retry count of low rate, but driver
doesn't implement yet, so add a dummy case to avoid message:

  rtw89_8852be 0000:03:00.0: c2h class 2 not support
