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.
