Log message:
Fix an alignment issue in iwx(4) Rx descriptors.
Split a 64-bit field, aligned at a 4-byte boundary, into two 32 bit fields.
Our driver does not use this field. Its definition does not matter to us,
as long as its size remains correct.
Fixes clang-15 warnings, which turn into compilation errors with -Werror.
