qca-wifi: CFR: Fix cookie lookup failure during RXTLV processing

37th bit is being set as an exchange between FW and ucode
to indicate that it is a DDR address to PCSS module.
As a result of which Cookie lookup fails while comparing
all 40 bits, since the physical address of DBR buffer 
does not match with the physical address of the received
buffer.

Since lower 36bits represents physical address,
Use only 4 least significant bits from higher 32bits along
with lower 32 bits while programming the physical address in
DBR SRNG. Format: ( low32 + 4 bits of high32 ).
