dm-verity-fec: pass down index_in_region instead of rsb

Replace 'rsb', which is a byte index, with 'index_in_region' which is a
block index.  The block index is slightly easier to compute, it matches
what fec_read_bufs() wants, and it avoids the mismatch between the name
and the units of the variable.  ('rsb' stood for "Reed-Solomon block",
but its units were bytes, not blocks.)

fec_decode_bufs() does want it as a byte index when computing
parity_block, but that's easily handled locally.

As long as the parameters to the log messages are being adjusted, also
eliminate the unnecessary casts to 'unsigned long long'.  %llu is the
correct way to print a u64 in the Linux kernel, as documented in
printk-formats.rst.  There's no PRIu64 macro like there is in userspace.
