fdasd: Skip partition check with the force option

Browse Source 
Before writing data to the disk, fdasd always checks whether a partition
is specified to prevent writing partition tables to a partition.

However, this also prevents the user from writing partition tables to
loop devices > loop0, even when the force option is specified.
Technically, those are not partitions.

Therefore, allow writing partition tables to partitions when the force
option is specified.

Fixes: #4
