RFR: JDK-8261601: free memory in early return in Java_sun_nio_ch_sctp_SctpChannelImpl_receive0

[Matthias Baesken]

There seems to be an early return in Java_sun_nio_ch_sctp_SctpChannelImpl_receive0 that misses freeing memory.

Potential leak of memory pointed to by 'newBuf'
I adjusted  the early return and added freeing memory .


Btw. while  adjusting  Java_sun_nio_ch_sctp_SctpChannelImpl_receive0  , I started  to wonder what happens to the allocated memory in  the same file in handleSendFailed  (  if ((addressP = malloc(dataLength)) == NULL)   )   in early return cases  incl. the CHECK_NULL , is there some deallocation missing there too ?
