wifi: rtlwifi: rtl8821ae: Fix C2H bit location in RX descriptor
commit 83d38df6929118c3f996b9e3351c2d5014073d87 upstream.
Bit 28 of double word 2 in the RX descriptor indicates if the packet is
a normal 802.11 frame, or a message from the wifi firmware to the
driver (Card 2 Host).
Commit f5678bfe1cdc ("rtlwifi: rtl8821ae: Replace local bit manipulation
macros") mistakenly made the driver look for this bit in double word 1,
causing packet loss and Bluetooth coexistence problems.
Fixes: f5678bfe1cdc ("rtlwifi: rtl8821ae: Replace local bit manipulation macros")
