scst_mem: Fix a memory leak triggered by the scst_user driver
Avoid that the following memory leak can occur:
- sgv_pool_alloc() is called with SGV_POOL_RETURN_OBJ_ON_ALLOC_FAIL
set, with neither SGV_POOL_NO_ALLOC_ON_CACHE_MISS nor
SGV_POOL_ALLOC_NO_CACHED set and with 'size' such that
sgv_max_local_pages < pages_to_alloc <= pool->max_cached_pages.
- sgv_get_obj() and sgv_alloc_arrays() succeed.
- sgv_alloc_sg_entries() fails.
- sgv_get_obj() returns the SGV object with no buffers.
- A call to sgv_pool_free() adds this object to the recycle list.
- sgv_pool_alloc() is called a second time with the same parameters.
- sgv_get_obj() retrieves the object that was previously added to
the recycle list.
- sgv_alloc_arrays() is called and overwrites the obj->sg_entries
pointer although it still points at allocated memory, resulting
in a memory leak.
