Subject: [PATCH 85/86] syscall: remove preadv and pwritev sys wrappers

Commit 76f1680 introduced sys wrappers for preadv and pwritev where these
syscalls are not supported for RHEL5. These functions are of actually no use
w.r.t downstream code as sys_pwritev is used only in bd xlator which is not
supported in downstream

Label: DOWNSTREAM ONLY
