nca_patch: Significantly reduce the stack usage size within SearchBucketEntry()

Previously this function was using ~16KB of stack (16528 bytes), which
was caused by the function arguments being taken by value rather than by
reference.

We can make this significantly lighter on the stack by taking them by
reference.
