openvswitch: Unionize ovs_key_ct_label with a u32 array.
Make the array of labels in struct ovs_key_ct_label an union, adding a u32 array of the same byte size as the existing u8 array. It is faster to loop through the labels 32 bits at the time, which is also the alignment of netlink attributes.

write+0x6c/0x1e0 vfs_write+0xd0/0x270 SyS_write+0x6c/0x110 system_call+0x38/0xe0 Examination of the queue showed a single reference (no PERCPU_COUNT_BIAS, and __PERCPU_REF_DEAD, __PERCPU_REF_ATOMIC set) and no requests. However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
