[PATCH -next] pga: dfl: pci: Make sure DMA related error check is not done twice

[Yusuf Khan]

In the case that the DMA 64 bit bit mask error check does not fail,
the error check will be done twice, this patch fixed that.

NOTE: This patch is only for use in the linux-next branch as the
commit that caused this bug happened there.
