log block manager: use unsigned int for next_block_id_
KUDU-1538 introduced 'next_block_id_' to keep track of unique block
ID that should be used for block creation. Currently, it is defined
as int64_t. However, it could be updated based on the value of
'max_block_id' which is uint64_t. Moreover, block IDs are defined
as uint64_t both on disk (fs.proto) and in memory (block_id.h), so
it makes more sense to treat 'next_block_id_' as uint64_t than to
convert it properly.
This patch changes the type of 'next_block_id_' to uint64_t to
avoid overflow due to conversion of unsinged int to int, which
can result in the reuse of an existing block ID. It does not add
a standalone test case because the failure can most likely occur
in specific test-only scenarios.
