cxl/mem: Fix a double shift bug
The CXL_FW_CANCEL macro is used with set/test_bit() so it should be a bit number and not the shifted value. The original code is the equivalent of using BIT(BIT(0)) so it's 0x2 instead of 0x1. This has no effect on runtime because it's done consistently and nothing else was using the 0x2 bit.
