[Qemu-devel] [PULL 23/26] block: Remove deprecated -drive geometry options

[Kevin Wolf <kwolf@redhat.com>]

The -drive options cyls, heads, secs and trans were deprecated in
QEMU 2.10. It's time to remove them.

hd-geo-test tested both the old version with geometry options in -drive
and the new one with -device. Therefore the code using -drive doesn't
have to be replaced there, we just need to remove the -drive test cases.
This in turn allows some simplification of the code.
