[COMMITTED 2/6] ada: Spurious maximum nesting level warnings

[Marc Poulhiès]

From: Justin Squirek <squi...@adacore.com>

This patch fixes an issue in the compiler whereby disabling style checks via
pragma Style_Checks ("-L") resulted in the minimum nesting level being zero
but the style still being enabled - leading to spurious maximum nesting level
exceeded warnings.

gcc/ada/

        * stylesw.adb (Set_Style_Check_Options): Disable max nesting level
        when unspecified

Tested on x86_64-pc-linux-gnu, committed on master.
