slip: fix MTU comparation operation when reallocating buffers
In sl_realloc_bufs() there is no reason to check if the requested MTU greater than or equal to the current MTU value as this function called only when requested MTU not equals to the current value. So, the ">=" operation can be safely replaced with the ">". Signed-off-by: Matvejchikov Ilya <matvejchikov@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
