dm integrity: fix invalid table returned due to argument count mismatch
commit5.4-rM2-2.2.x-imx-squashed7fc2e47f40
upstream. If the flag SB_FLAG_RECALCULATE is present in the superblock, but it was not specified on the command line (i.e. ic->recalculate_flag is false), dm-integrity would return invalid table line - the reported number of arguments would not match the real number. Fixes:468dfca38b
