rombios/ata Remove another needless trap from the int 0x13 hotpath

The return value from await_ide() is always ignored, and most calls to
await_ide() immediately reread the status register.

Therefore, making await_ide() return the last value of the status register
removes a further two traps on the int 0x13 path.
