[PATCH bpf-next 1/7] bpf: Remove unnecessary wait from bpf_map_copy_value()

[Hou Tao <houtao@xxxxxxxxxxxxxxx>]

From: Hou Tao <houtao1@xxxxxxxxxx>

Both map_lookup_elem() and generic_map_lookup_batch() use
bpf_map_copy_value() to lookup and copy the value, and there is no
update operation in bpf_map_copy_value(), so just remove the invocation
of maybe_wait_bpf_programs() from it.

Fixes: 15c14a3dca42 ("bpf: Add bpf_map_{value_size, update_value, map_copy_value} functions")
