radeonsi: convert dispatch packet to little endian 

The parameters for the compute engine are wrong when using
an E8860 on a big endian machine.
To fix this, convert the contents of struct dispatch_packet
to little endian.

This ensures that get_global_id(0) and similar functions
in the OpenCL code get the correct endian values, and
makes my simple OpenCL program work correctly.
