cxl: Remove always true condition for cxlctl_validate_hw_command()

smatch warnings:
drivers/cxl/core/features.c:441 cxlctl_validate_hw_command() warn: always true condition '(scope >= 0) => (0-u32max >= 0)'

Remove the check entirely as it has no effect. Expectation is both of these
operations should be allowed for all check levels. They are read only and
have no change effects.
