debugfs: improve dump_mmp handling

If MMP is not enabled on a filesystem (s_mmp_block == 0), print this
clearly rather than "MMP: block number beyond filesystem range".

Add an option to "debugfs dump_mmp" to specify the MMP block number
instead of getting it from the superblock s_mmp_block field.
