commit 7eb1e47696aa231b1a567846bbe3a1e1befe1854 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.
Fixes: b6f3f28f604b ("block: add overflow checks for Amiga partition support")
