greybus: greybus_protocols.h/es2: Ensure __le32 is used not u32
There is a dangling u32 in es2/greybus_protocols.h that is only obvious when you try to compile up gbsim. We need to do a cpu_to_le32 and declare the 32-bit int in the header as __le32. This patch does that and splits out the assignment of the req->flags parameter to a temporary variable to allow for later printing.
