hsr: annotate data-race around hsr->sequence_nr

Browse source

hsr->sequence_nr is incremented from the transmit paths under
hsr->seqnr_lock, but hsr_fill_info() reads it without holding
this lock.

Use WRITE_ONCE() in the two writers, so that a matching
READ_ONCE() can be used in hsr_fill_info().
