[PATCH 1/6] fiemap: Remove blocksize variable

[Nikolay Borisov <nborisov@suse.com>]

The blocksize variable was hardcoded to 512 bytes and was passed to various
functions. This introduced a lot of redundancy since we can just as well use
the BTOBBT macro. So let's do that and eliminate all usage of the blocksize var.
No functional changes.
