Michael Schmitz 899cc8f798 block/partition: fix signedness issue for Amiga partitions ...

commit 7eb1e47696 upstream.

Making 'blk' sector_t (i.e. 64 bit if LBD support is active) fails the
'blk>0' test in the partition block loop if a value of (signed int) -1 is
used to mark the end of the partition block list.

Explicitly cast 'blk' to signed int to allow use of -1 to terminate the
partition block linked list.
