flowcache: Fix kernel panic in flow_cache_flush_task
flow_cache_flush_task references a structure member flow_cache_gc_work
where it should reference flow_cache_flush_task instead.
Kernel panic occurs on kernels using IPsec during XFRM garbage
collection. The garbage collection interval can be shortened using the
following sysctl settings:
net.ipv4.xfrm4_gc_thresh=4
net.ipv6.xfrm6_gc_thresh=4
With the default settings, our productions servers crash approximately
once a week. With the settings above, they crash immediately.
Fixes: ca925cf1534e ("flowcache: Make flow cache name space aware")
