ata: sata_sil24: Remove call to memset after dmam_alloc_coherent
In commit af7ddd8a627c ("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),, dmam_alloc_coherent has already zeroed the memory. So memset is not needed. Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
