selftests: ublk: Use ARRAY_SIZE() macro to improve code

Browse Source 
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 ec12009318 ("selftests: ublk: fix ublk_find_tgt()")
wherever appropriate to maintain consistency.
