[PATCH bpf-next v2] bpf: update docs on CONFIG_FUNCTION_ERROR_INJECTION

[PATCH bpf-next v2] bpf: update docs on CONFIG_FUNCTION_ERROR_INJECTION

[Martin Kelly]

The documentation says CONFIG_FUNCTION_ERROR_INJECTION is supported only
on x86. This was presumably true at the time of writing, but it's now
supported on many other architectures too. Drop this statement, since
it's not correct anymore and it fits better in other documentation
anyway.
