ahci: Soften up the dmesg on SB600 PMP softreset failure recovery

Browse Source 
Too strong words led to spurious bug reports: Novell bugzilla #527748,
RedHat bugzilla #468800. This patch is used to soften up the dmesg on
SB600 PMP softreset failure recovery, so as to remove the scariness and
concern from community.
