src: use UV_EINVAL instead of EINVAL in udp_wrap

Currently if the buffer size exceeds the maximum int size the following
error will be thrown:
dgram.js:180
    throw new errors.Error('ERR_SOCKET_BUFFER_SIZE', e);
    ^

Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer size: Error:
Unknown system error 22: Unknown system error 22, uv_recv_buffer_size
    at bufferSize (dgram.js:180:11)

It looks like perhaps UV_EINVAL was intended to give the following error
message instead:
dgram.js:180
    throw new errors.Error('ERR_SOCKET_BUFFER_SIZE', e);
    ^

Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer size: Error:
EINVAL: invalid argument, uv_recv_buffer_size
    at bufferSize (dgram.js:180:11)

This commit changes EINVAL to use UV_EINVAL.
