Re: start-up failure at SVN r314889

Per Hans .. this should fix it:

r314953 | hselasky | 2017-03-09 04:17:43 -0500 (Thu, 09 Mar 2017) | 9 lines
Changed paths:
    M /head/sys/compat/linuxkpi/common/src/linux_work.c

Don't create any threads before SI_SUB_INIT_IF in the LinuxKPI. Else
kthread_add() will assert it is called too soon. This fixes a startup
issue when COMPAT_LINUXKPI is in enabled the kernel configuration
file.
