[ Upstream commit 41349672e3cbc2e8349831f21253509c3415aa2b ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/xen/pvcalls-front.c: In function pvcalls_front_sendmsg:
drivers/xen/pvcalls-front.c:543:25: warning: variable bedata set but not used [-Wunused-but-set-variable]
drivers/xen/pvcalls-front.c: In function pvcalls_front_recvmsg:
drivers/xen/pvcalls-front.c:638:25: warning: variable bedata set but not used [-Wunused-but-set-variable]

They are never used since introduction.
