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.  

v2->v1:
- Instead of freeing part of fields in collect_image_check(), do discard the old check object and allocate a new one in the caller to make more sense.(suggested by Max Reitz)

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