Subject: [PATCH next] cxl: fix return value in cxlctl_validate_set_features()

The cxlctl_validate_set_features() function is type bool.  It's supposed
to return true for valid requests and false for invalid.  However, this
error path returns ERR_PTR(-EINVAL) which is true when it was intended to
return false.

Fixes: f76e0bbc8bc3 ("cxl: Update prototype of function get_support_feature_info()")
