ENA_MSLEEP() and ENA_UDELAY() were expecting different behavior - the
first one is expecting driver to sleep, while the other, to busy wait.

For both cases, the rte_delay_(u|m)s() function was used, which could
be either sleep or block, depending on the configuration.

To make the macros valid, the operations should be specified directly.
Because of that, the rte_delay_us_sleep() and rte_delay_us_block() are
now being used.
