[PATCH] ahci: fix status register check in ahci_softreset
ahci_softreset() used to use ahci_tf_read() which reads D2H_REG area
to check for the Status register. However, this area is zeroed on
initialization and not set by initial signature FIS. Replace it with
ahci_check_status().
This bug prevented CLO code from being activated whenever BSY and/or
DRQ is set prior to softreset. This fix makes
AHCI_FLAG_RESET_NEEDS_CLO flag redundant.
