Subject: [PATCH] alpha: remove the needless aliases osf_{readv,writev}

Commit 987f20a9dcce ("a.out: Remove the a.out implementation") removes
CONFIG_OSF4_COMPAT and its functionality. Hence, sys_osf_{readv,writev}
are now just aliases of sys_{readv,writev}.

Remove these needless aliases.

Linus says: minor cleanup... - Janitor says: Yes, that is my job!

Completely untested.

alpha maintainers, please pick this minor cleanup for your -next tree.
