[PATCH v2 3/4] crypto: qat - disable AER if an error occurs in probe functions

[Giovanni Cabiddu <giovanni.cabiddu@xxxxxxxxx>]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

If an error occurs after a 'adf_enable_aer()' call, it must be undone by a
corresponding 'adf_disable_aer()' call, as already done in the remove
function.
