dcdbas: force SMI to happen when expected
The dcdbas driver can do an I/O write to cause a SMI to occur. The SMI handler
looks at certain registers and memory locations, so the SMI needs to happen
immediately. On some systems I/O writes are posted, though, causing the SMI to
happen well after the "outb" occurred, which causes random failures. Following
the "outb" with an "inb" forces the write to go through even if it is posted.
