[igt-dev] [PATCH i-g-t 2/3] tests/kms_cursor_crc: fix truncated warning

[Matthew Auld]

Looks reasonable to just increase the size of 'name' to avoid the
potential truncation:

../tests/kms_cursor_crc.c: In function ‘run_size_tests.constprop’:
../tests/kms_cursor_crc.c:699:50: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size between 4 and 14 [-Wformat-truncation=]
