Before hardreset, ahci initialized stat part of received FIS area to 0xff to wait for the first D2H Reg FIS which would change the value to device ready state. This used to work but now libata considers status value of 0xff as device not present making this wait prone to failure. This patch makes ahci use 0x80 for the wait stat value instead of 0xff to fix the above problem.

For the future, please make sure to include the "---" terminator prior to the diffstat, otherwise it will get copied into the kernel changelog.
