btrfs: fix uninitialized variable warnings in __set_extent_bit and convert_extent_bit
We will pass in the parent and p pointer into our tree_search function
to avoid doing a second search when inserting a new extent state into
the tree. However because this is conditional upon passing in these
pointers the compiler seems to think these values can be uninitialized
if we're using -Wmaybe-uninitialized. Fix this by initializing these
values.
