perf probe: Show the error reason comes from invalid DSO
Show the reason of error when dso__load* fails. This shows when user
gives wrong kernel image or wrong path.
Without this, perf probe shows an obscure message:
----
$ perf probe -k ~/kbin/linux-3.x86_64/vmlinux -L vfs_read
Failed to find path of kernel module.
Error: Failed to show lines.
----
With this, perf shows appropriate error message:
----
$ perf probe -k ~/kbin/linux-3.x86_64/vmlinux -L vfs_read
Failed to find the path for kernel: Mismatching build id
Error: Failed to show lines.
----
And:
----
$ perf probe -k /non-exist/kernel/vmlinux -L vfs_read
Failed to find the path for kernel: No such file or directory
Error: Failed to show lines.
