[PATCH 5.15 17/20] selftests/vm: remove ARRAY_SIZE define from individual tests

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Shuah Khan <skhan@linuxfoundation.org>

commit e89908201e2509354c40158b517945bf3d645812 upstream.

ARRAY_SIZE is defined in several selftests. Remove definitions from
individual test files and include header file for the define instead.
ARRAY_SIZE define is added in a separate patch to prepare for this
change.

Remove ARRAY_SIZE from vm tests and pickup the one defined in
kselftest.h.
