Filipe Manana aee10fe4e4 btrfs: reduce size of struct tree_mod_elem ...

Several members are used for specific types of tree mod log operations so
they can be placed in a union in order to reduce the structure's size.

This reduces the structure size from 112 bytes to 88 bytes on x86_64,
so we can now use the kmalloc-96 slab instead of the kmalloc-128 slab.
