s390/dasd: Refactor prefix_LRE() and related functions
We already have define_extent() that prepares necessary data for the
Define Extent CCW. The exact same thing is done in prefix_LRE().
Remove the duplicate code and move commands that were only used in
combination with the Prefix command to define_extent(). One of these
commands needs the blocksize to be specified. Add the blksize parameter
to define_extent() to account for that.
In addition, the check_XRC() function can be made more generic. Do this
and remove the Prefix-specific check_XRC_on_prefix() function.
Furthermore, prefix_LRE() uses fill_LRE_data() to prepare Locate Record
Extended data. Rename the function to fit the scheme better and make it
usable outside of the Prefix context by adding the corresponding CCW
command.
