Windows compilation gives us a splat:
In file included from ../drivers/dma/idxd/idxd_pci.c:10:
In file included from ..\drivers\dma\idxd/idxd_internal.h:11:
..\drivers\dma\idxd/idxd_hw_defs.h:46:21: error: expected member name or
';' after declaration specifiers
uint16_t __reserved[13];
~~~~~~~~ ^
1 error generated.
Ironically, __reserved is probably a reserved token.
Some drivers that build fine on Windows have structs with a "reserved"
field, let's go with this.
Fixes: 82147042d062 ("dma/idxd: add datapath structures")

Yes, and it's used in system headers for static analyzer annotations:

Tested via CI@UNH.
Applied.
