dev-amdgpu: Fix size issue in interrupt handler

The data allocated for the DMA request used to send an interrupt cookie
was too large. This was causing the memcpy to occasionally seg fault due
to reading past the bounds of the source parameter (the interrupt cookie
struct). Correct the size and add a compile time check to ensure it is
the correct number of bytes expected by the driver.
