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

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 66602c83dcb6a5d82772d88ae7a32cd4a1213528
("cmd64x: use interrupt status from MRDMODE register (take 2)").

Extra thanks to Martin for reporting and bisecting the issue.
