Use ARRAY_SIZE() macro while calculating size of an array to improve
code readability and reduce potential sizing errors.
Implement this suggestion given by spatch tool by running
coccinelle script - scripts/coccinelle/misc/array_size.cocci
Follow ARRAY_SIZE() macro usage pattern in ublk.c introduced by,
commit ec120093180b9 ("selftests: ublk: fix ublk_find_tgt()")
wherever appropriate to maintain consistency.

Testing:
* build checked for testing/selftests/ublk
* tested by running
$ ./kublk --help
Which exercises the impacted code path.
