dm integrity: fix the maximum number of arguments

Advance the maximum number of arguments from 9 to 15 to account for all potential feature flags that may be supplied. Linux 4.19 added "meta_device" (356d9d5) and "recalculate" (a3fcf72) flags. Commit 468dfca added "sectors_per_bit" and "bitmap_flush_interval". Commit 84597a4 added "allow_discards". And the commit d537858 added "fix_padding".
