compat: Initialize IPv4 reassembly secret timer
The RHEL 7 kernels expect the secret timer interval to be initialized
before calling the inet_frags_init() function. By not initializing it
the inet_frags_secret_rebuild() function was running on every tick
rather than on the expected interval. This caused occasional panics
from page faults when inet_frags_secret_rebuild() would try to rearm a
timer from the openvswitch kernel module which had just been removed.
Also remove the prior, and now unnecessary, work around.
