tracing/kprobe: Fix kprobe_on_func_entry() modification

stable inclusion
from linux-4.19.208
commit 6cfbbb961bb94de85455fe35140b1350c7ccb76c

--------------------------------

The commit 960434acef37 ("tracing/kprobe: Fix to support kretprobe
events on unloaded modules") backport from v5.11, which modifies the
return value of kprobe_on_func_entry(). However, there is no adaptation
modification in create_trace_kprobe(), resulting in the exact opposite
behavior. Now we need to return an error immediately only if
kprobe_on_func_entry() returns -EINVAL.
