staging: rtl8192e: remove bogus __packed annotations

The rtllib_rxb structure contains a pointer, so this is not a hardware
structure but could benefit from loading the pointer in a single
instruction rather than assembling it from four or eight individual
bytes.

Both structures are allocated as part of larger structure that
already enforce at least a 4-byte alignment, so there is no
reason to ever have to deal with misaligned definitions.
