net/i40e/base: fix resource leakage

In the i40e_init_arq function, when the i40e_config_arq_regs function
returns from processing failure, the previously applied arq_bufs resource
is not released, which leads to leakage.
The patch is processed in the same way as the i40e_init_asq function,
maintaining a unified coding style.
