[Btrfs-devel][PATCH]Properly update right_nritems in push_leaf_left

[Yan Zheng]

Hello,

The codes that fixup the right leaf and the codes that dirty the
extnet buffer use the variable 'right_nritems' ,  both of them expect
'right_nritems' is the number of items in right leaf after the push.

Regards
YZ
