ima: fix memory leak in ima_release_policy
When the "policy" securityfs file is opened for read, it is opened as a
sequential file. However, when it is eventually released, there is no
cleanup for the sequential file, therefore some memory is leaked.
This patch adds a call to seq_release() in ima_release_policy() to clean up
the memory when the file is opened for read.
Fixes: 80eae209d63a IMA: allow reading back the current policy
