ipc: adjust proc_ipc_sem_dointvec definition to match prototype
Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
changed ctl_table.proc_handler to take a kernel pointer. Adjust the
signature of proc_ipc_sem_dointvec to match ctl_table.proc_handler which
fixes the following sparse error/warning:
ipc/ipc_sysctl.c:94:47: warning: incorrect type in argument 3 (different address spaces)
ipc/ipc_sysctl.c:94:47: expected void *buffer
ipc/ipc_sysctl.c:94:47: got void [noderef] __user *buffer
ipc/ipc_sysctl.c:194:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces))
ipc/ipc_sysctl.c:194:35: expected int ( [usertype] *proc_handler )( ... )
ipc/ipc_sysctl.c:194:35: got int ( * )( ... )
Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
