cmd64x: don't clear the other channel's interrupt

Browse source

Make sure to not clear the other IDE channel's interrupt when clearing an IDE
interrupt via the MRDMODE register.

Thanks to Bart for finding a coding mistake.

Bart:

This fixes regression from commit 66602c83dc
("cmd64x: use interrupt status from MRDMODE register (take 2)").

Extra thanks to Martin for reporting and bisecting the issue.
