Now that the sanitization process will make pages available by calling
sgx_free_epc_page(), sgx_setup_epc_section() should not touch to
sgx_nr_free_pages. This will result sgx_nr_free_pages to contain 2x the
number of actual free pages. Simply, remove the statement.

Fixes: 51ab30eb2ad4 ("x86/sgx: Replace section->init_laundry_list with sgx_dirty_page_list")
