block/partition: fix signedness issue for Amiga partitions
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.
