wifi: rtlwifi: rtl8192de: Don't read register in _rtl92de_query_rxphy…

…status

Instead of reading bit 9 of RFPGA0_XA_HSSIPARAMETER2 every time a frame
is received, just use rtlphy->cck_high_power, which is initialised in
_rtl92d_phy_bb_config(). That bit never changes anyway.

With this change _rtl92de_query_rxphystatus() can be shared with the
upcoming USB driver. The USB driver can't read registers in this
function because register reading can sleep.

Compile tested only.
