ada: Remove dead detection of recursive inlined subprograms

Inlining of subprogram calls happens in routine Expand_Inlined_Call
which calls Establish_Actual_Mapping_For_Inlined_Call. Both routines
had detection of recursive calls. The detection in the second routine
was dead code.

gcc/ada/

	* inline.adb (Establish_Actual_Mapping_For_Inlined_Call):
	Remove detection of recursive calls.
