bpf: Fix memory leak in __lookup_instance error path
When __lookup_instance() allocates a func_instance structure but fails
to allocate the must_write_set array, it returns an error without freeing
the previously allocated func_instance. This causes a memory leak of 192
bytes (sizeof(struct func_instance)) each time this error path is triggered.
Fix by freeing 'result' on must_write_set allocation failure.
Fixes: b3698c356ad9 ("bpf: callchain sensitive stack liveness tracking using CFG")
