f2fs: rework fault injection handling to avoid a warning
When CONFIG_F2FS_FAULT_INJECTION is disabled, we get a warning about an unused label: fs/f2fs/segment.c: In function '__submit_discard_cmd': fs/f2fs/segment.c:1059:1: error: label 'submit' defined but not used [-Werror=unused-label] This could be fixed by adding another #ifdef around it, but the more reliable way of doing this seems to be to remove the other #ifdefs where that is easily possible. By defining time_to_inject() as a trivial stub, most of the checks for CONFIG_F2FS_FAULT_INJECTION can go away. This also leads to nicer formatting of the code.
