Hello All,
	As per KK's review comment received on Nov 8 about the free_shared_mem function, Iam sending the following patch.

The change log includes:

1. Break from the main 'for loop' if ba[i] is NULL.

2. In the second level 'for loop', if ba[i][j] is NULL, instead of
continuing as was done previously, we now free the ba[i] pointer and
break from the main 'for loop'.

3. In the 'while loop' inside the second tier 'for loop', if any of the
three pointers (ba or ba->ba_0_org or ba->ba_1_org) is found to be NULL,
then ba[i], ba[i][j] and the non NULL buffer pointer if any
(ba_0_org or ba_1_org) is freed and break from the main 'for loop'.
