[PATCH net 2/3] net: inet_recvmsg(): Remove unnecessary bitwise operation

The flag `MSG_DONTWAIT' is handled by passing an argument through
the dedicated parameter `nonblock' of the function `tcp_recvmsg()'.

Presumably because `MSG_DONTWAIT' is handled so explicitly, it is
unset in the collection of flags that are passed to `tcp_recvmsg()';
yet, this unsetting appears to be unnecessary, and so this commit
removes the bitwise operation that performs the unsetting.
