btrfs: mark leaf space and overflow checks as unlikely on insert and extension

We have several sanity checks when inserting or extending items in a btree
that verify we didn't overflow the leaf or access a slot beyond the last
one. These are cases that are never expected to be hit so mark them as
unlikely, allowing the compiler to potentially generate better code.
