wifi: rtw89: phy: skip trailing 8-byte zeros of PHY status IE for RTL8922D

Hardware reports a list of PHY status IE. In monitor mode, IE-09 of
PHY status is enabled, and the report contains trailing 8-byte zeros,
causing failed to parse and drop all IE information.

The 8 zeros are recognize as IE type 0, but length of type 0 must be
not 8 (reference to rtw89_phy_gen_def::physt_ie_len[0]).
Check and skip them.
