gtp: use __GFP_NOWARN to avoid memalloc warning
gtp hashtable size is received by user-space. So, this hashtable size could be too large. If so, kmalloc will internally print a warning message. This warning message is actually not necessary for the gtp module. So, this patch adds __GFP_NOWARN to avoid this message.
