[LU-15003] use client enc_pool for fscrypt https://jira.whamcloud.com/browse/LU-15003 Lustre <p>According to Sebastien's <a href="https://www.eofs.eu/_media/events/lad20/lustre-client-encryption.pdf" class="external-link" target="_blank" rel="nofollow noopener">fscrypt presentation at LAD'20</a>, the use of bounce buffers reduces fscrypt performance by up to 30%.</p> <p>This can be replaced by using preallocated pages in <tt>enc_pool</tt> from Kerberos, so that pages do not need to be allocated/freed for every RPC.</p> LU-15003
