Code cleanup.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* par-prag.adb (Check_Arg_Count): Change parameter type from Int
	to Nat, because this parameter is compared to Arg_Count variable
	which is of type Nat. Also, it wouldn't make sense to check for
	negative number of pragma arguments.
