Xiubo Li 35b092d3b5 ceph: put the requests/sessions when it fails to alloc memory ...

[ Upstream commit 89d43d0551 ]

When failing to allocate the sessions memory we should make sure
the req1 and req2 and the sessions get put. And also in case the
max_sessions decreased so when kreallocate the new memory some
sessions maybe missed being put.

And if the max_sessions is 0 krealloc will return ZERO_SIZE_PTR,
which will lead to a distinct access fault.
