kobject: Transmit return value of call_usermodehelper() to caller
kobject_uevent_env() drops the return value of call_usermodehelper().
It will make upper caller, such as dm_send_uevents(), to lose error
information.
BTW, Previously kobject_uevent_env() transmitted return of
call_usermodehelper() to callers, but
commit 5f123fbd80f4f788554636f02bf73e40f914e0d6
"[PATCH] merge kobject_uevent and kobject_hotplug" removed it.
