Most of the search , pointing it is old backup ( more then 7 day ), some doc say backup corrupted etc etc. Instead going for whole story that how reached to conclusion, let we tell you the finding.
We found the mount option for /dba/share/MYDB ( where we copied backup from source ) not correct
...that's why getting error. We changed it to
rw,bg,intr,hard,timeo=600,wsize=32768,rsize=32768,nfsvers=3,tcp,noacl 0 0
After this change we able to restore control file and rest of the backup successfully
