[PATCH] btrfs: Use next_leaf instead of next_item when slots > nritems

After calling btrfs_search_slot is a common pratice to check if the
slot found isn't bigger than number of slots in the current leaf, and if
so, search for the same key in the next leaf by calling btrfs_next_leaf,
which calls btrfs_next_old_leaf to do the job.

Calling btrfs_next_item in the same situation would end up in the same
code flow, since

* btrfs_next_item
  * btrfs_next_old_item
    * if slot >= nritems(curr_leaf)
      btrfs_next_old_leaf

Change btrfs_verify_dev_extents and calculate_emulated_zone_size
functions to use btrfs_next_leaf in the same situation.

 Please let me know if I'm missing something obvious here, but all other places
 who check for slot >= nritems are calling next_leaf...

 I found this code while checking all btrfs_search_slot users.
