uvesafb: improve parameter handling.
1) Now module_param(..., invbool, ...) requires a bool, and similarly module_param(..., bool, ...) allows it, change pmi_setpal to a bool. 2) #define param_get_scroll to NULL, since it can never be called (perm argument to module_param_named is 0). 3) Return -EINVAL from param_set_scroll if the value is bad, so it's reported. Note that I don't think the old fb_get_options() is required for new drivers: the parameters automatically work as uvesafb.XXX=... anyway.
