tst-realloc: do not check for errno on success [BZ #22611]

Browse Source 
POSIX explicitly says that applications should check errno only after
failure, so the errno value can be clobbered on success as long as it
is not set to zero.

Changelog:
	[BZ #22611]
	* malloc/tst-realloc.c (do_test): Remove the test checking that errno
	is unchanged on success.
