[libata] sata_sil: fix used-uninit warning
Init 'serror' to silence the following warning: drivers/ata/sata_sil.c: In function ‘sil_interrupt’: drivers/ata/sata_sil.c:453:14: warning: ‘serror’ may be used uninitialized in this function [-Wuninitialized] This is not a 'can never happen' but is nonetheless extremely unlikely. The easiest and cleanest warning fix is simply to init the var, rather than worry about marking the var uninit-ok. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
