libparted: Remove fdasd geometry code from alloc_metadata (#1244833)

commit db20944f changed how the trailing_metadata_end is calculated in
dasd_alloc_metadata, removing the need for setting up the anchor struct.
But dasd_alloc_metadata can be called in various contexts, and the
arch_specific->fd may or may not be valid during these calls. This can
result in unpredictable crashes when it uses a stale fd and tries to run
the file image code in fdasd_get_geometry instead of the device code.

The solution is to just drop the unneeded code, and to remember that
arch_specific->fd should only be used when ped_device_open has first
been called.

Resolves: rhbz#1244833
