[PATCH 0/2] fix two small memleaks

[Pan Nengyuan]

This series fix two small memleaks.
1. 'crypto_opts' forgot to free in qcow2_close(), do this cleanup in 
qcow2_close();
2. Do free filename/format in collect_image_check() when we re-allocate it.  

Pan Nengyuan (2):
  block/qcow2: do free crypto_opts in qcow2_close()
  qemu-img: free memory before re-assign

 block/qcow2.c | 1 +
 qemu-img.c    | 2 ++
