[PATCH parted] msdos_partition_is_flag_available: fix hidden on extended

[Hans de Goede]

From: David Cantrell <address@hidden>

Since the hidden flag cannot be set on extended partitions,
msdos_partition_is_flag_available() should return 0 for hidden on
extended partitions. Also change msdos_partition_get_flag()
to always return 0 for hidden on extended partitions.
* libparted/labels/dos.c (msdos_partition_is_flag_available):
Return 0 for hidden on extended partitions.
* libparted/labels/dos.c (msdos_partition_get_flag):
Always return 0 for hidden on extended partitions.
