Summary
selinux: fix double free of cond_list on error paths
Details

In the Linux kernel, the following vulnerability has been resolved:

selinux: fix double free of cond_list on error paths

On error path from condreadlist() and duplicatepolicydbcondlist() the condlistdestroy() gets called a second time in caller functions, resulting in NULL pointer deref. Fix this by resetting the condlistlen to 0 in condlist_destroy(), making subsequent calls a noop.

Also consistently reset the cond_list pointer to NULL after freeing.

[PM: fix line lengths in the description]
