ide-cd: unify transfer padding in cdrom_newpc_intr()

* 'thislen' is always <= cmd->nleft for non-fs requests so the transfer
  padding inside the 'while (thislen > 0)' loop can happen only for fs
  requests -- then move it out of the loop and unify with the transfer
  padding for non-fs requests ('thislen' == 'len' for fs requests).

* blk_dump_rq_flags() dumps all request flags so it is enough to pass
  only the function name to it.

* Update my Copyrights while at it.
