[PATCH v2 1/2] btrfs: change num_items type from u64 to unsigned int

[Alexandru Moise]

The value of num_items that start_transaction() ultimately
always takes is a small one, so a 64 bit integer is overkill.

Also change num_items for btrfs_start_transaction() and
btrfs_start_transaction_lflush() as well.

v2: followed dave's suggestion of all num_items equivalents to be
unsigned ints.
