We never allocate the ceph_buffer and buffer separtely, so use a single
constructor.
Disallow put on NULL buffer; make the caller check.

Error handling code following a kmalloc should free the allocated data.
The semantic match that finds this problem is as follows:

Inode cache and inode operations. We also include routines to
incorporate metadata structures returned by the MDS into the client
cache, and some helpers to deal with file capabilities and metadata
leases. The bulk of that work is done by fill_inode() and
fill_trace().
