[PATCH resend] perf machine: Pass correct string to dso__adjust_kmod_long_name

[Wang Nan]

There's a mistake in dso__adjust_kmod_long_name() that, it use strdup()
to dup the new long_name of a dso, but passes the original string
to dso__set_long_name(). Which causes random crash during cleanup.

Fixes: c03d5184f0e9("perf machine: Adjust dso->long_name for offline module")
