linux mseal PRE wrapper should First check for overflow

According to https://docs.kernel.org/next/userspace-api/mseal.html
mseal returns -EINVAL when Address range (addr + len) overflow. The
LTP test mseal02 checks this. So do this check first before checking
for valid_client_addr (which returns -ENOMEM).
