[PATCH] dma/idxd: fix return value for pci device commands

[Kevin Laatz <kevin.laatz@intel.com>]

When sending a command to an idxd device via pci bar, the response from
HW is checked to ensure it was successful. The response was incorrectly
being negated before being returned by the function, meaning error codes
cannot be checked against the HW specification.

This patch fixes the return values of the function by removing the
negation.
