[Ada] Remove redundant condition for Image attribute and Ada version

[Ada] Remove redundant condition for Image attribute and Ada version

[Pierre-Marie de Rodat]

[-- Attachment #1: Type: text/plain, Size: 306 bytes --]

Routine Error_Msg_Ada_2012_Feature includes a test on Ada_Version, so
there is no need to explicitly test the same condition just before the
call.

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

gcc/ada/

	* sem_attr.adb (Analyze_Image_Attribute): Remove redundant
	condition; add a missing header box.
