platform/x86: hp-bioscfg: move mutex_lock() down in hp_add_other_attributes()
commit 5736aa9537c9b8927dec32d3d47c8c31fe560f62 upstream.
attr_name_kobj's memory allocation is done with mutex_lock() held, this
is not needed.
Move allocation outside of mutex_lock() so unlock is not needed when
allocation fails.
