libata: remove superfluous NULL pointer checks
host->ports[] always contain pointers to valid port structures since
a "dummy port" structure is used in case if there is no physical port.
This patch takes care of two entries from Dan's list:
drivers/ata/sata_sil.c +535 sil_interrupt(13) warning: variable derefenced before check 'ap'
drivers/ata/sata_mv.c +2517 mv_unexpected_intr(6) warning: variable derefenced before check 'ap'
and of another needless NULL pointer check in pata_octeon_cf.c.
