qed: Fix mask for physical address in ILT entry
[ Upstream commit fdd13dd350dda1826579eb5c333d76b14513b812 ]
ILT entry requires 12 bit right shifted physical address.
Existing mask for ILT entry of physical address i.e.
ILT_ENTRY_PHY_ADDR_MASK is not sufficient to handle 64bit
address because upper 8 bits of 64 bit address were getting
masked which resulted in completer abort error on
PCIe bus due to invalid address.
Fix that mask to handle 64bit physical address.
Fixes: fe56b9e6a8d9 ("qed: Add module with basic common support")
