[SCSI] aacraid: Relax the tight timeout loop on fib commands
The loop that waited for syncronous fib commands was causing a CPU stall
when a timeout actually occured.
1) Switch to using a more accurate timeout mechanism.
2) Do not pace the loop with udelay(). Use cpu_relax() to allow for
scheduling to occur.
