[igt-dev] [V2 i-g-t] tests/kms_cursor_crc: Fix SIGABRT in dynamic subtests

[Bhanuprakash Modem <bhanuprakash.modem@intel.com>]

All subtests must report success/fail instead of crashing out.

V2:
- Fix the coverage of max-size tests

Fixes: 9494d53d ("tests/kms_cursor_crc: Convert tests to dynamic")
