ACPI / osl: Kill macro INVALID_TABLE(). 



The macro INVALID_TABLE() is defined like this:

 #define INVALID_TABLE(x, path, name)                                    \
         { pr_err("ACPI OVERRIDE: " x " [%s%s]\n", path, name); continue; }

And it is used like this:

	for (...) {
		...
		if (...)
			INVALID_TABLE()
		...
	}

The "continue" in the macro makes the code hard to understand.

And also, this macro is only used several times in a single file.
As suggested by Joe Perches <joe@perches.com>, we can remote it and
use pr_err directly.

So after this patch, this macro is removed, and pr_err() is used
like this:

	for (...) {
		...
		if (...) {
			pr_err("ACPI OVERRIDE: ......");
			continue;
		}
		...
	}
