Subject: [PATCH] Fix SPARC64 unaligned access in zd_mac_rx

I'm running zd1211rw on SPARC64 and was getting a lot of "unaligned access" messages in dmesg. I tracked the problem down to this line, and changing the cast to a memcpy fixes the issue.

Please CC me with any comments as I am not subscribed to the list.
