Subject: vrf: don't check for dstats and rth in uninit path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a4a27d3bde1c9cd8159c86a79796348cab90140;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vrf: don't check for dstats and rth in uninit path

dstats and rth are always present because we fail the device registration
if they can't be allocated in vrf_init() (ndo_init) so drop the unnecessary
checks.
