[PATCH] Revert "hw/sparc64/niagara: Use blk_name() instead of open-coding it"

[Markus Armbruster <armbru@redhat.com>]

This reverts commit 1881f336a33a8a99cb17ab1c57ed953682e8e107.

This commit breaks "-drive if=pflash,readonly=on,file=image.iso".  It
claims to merely replace an open-coded version of blk_name() by a
call, but that's not the case.  Sorry for the inconvenience!
