[PATCH 5.11 151/775] selftests/bpf: Dont exit on failed bpf_testmod unload

[Greg Kroah-Hartman]

From: Andrii Nakryiko <and...@kernel.org>

[ Upstream commit 86ce322d21eb032ed8fdd294d0fb095d2debb430 ]

Fix bug in handling bpf_testmod unloading that will cause test_progs exiting
prematurely if bpf_testmod unloading failed. This is especially problematic
when running a subset of test_progs that doesn't require root permissions and
doesn't rely on bpf_testmod, yet will fail immediately due to exit(1) in
unload_bpf_testmod().

Fixes: 9f7fa225894c ("selftests/bpf: Add bpf_testmod kernel module for testing")
