Subject: [PATCH 1/2] fat: remove i_version handling from fat_update_time

commit 6bb885ecd746 (fat: add functions to update and truncate
timestamps appropriately") added an update_time routine for fat. That
patch added a section for handling the S_VERSION bit, even though FAT
doesn't enable SB_I_VERSION and the S_VERSION bit will never be set when
calling it.

Remove the section for handling S_VERSION since it's effectively dead
code, and will be problematic vs. future changes.
