[PATCH] xfs_db: improve argument naming in set_cur and set_iocur_type

[Bill O'Donnell <billodo@redhat.com>]

In set_cur and set_iocur_type, the current naming for arguments
type, block number, and length are t, d, and c, respectively.
Replace these with more intuitive and descriptive names:
type, blknum, and len. Additionally remove extra blank line
in io.c.
