irq.h: build assert removal from irq.h

This diff removes a build assert that no longer makes
sense due to the fact the MAX_IRQ_PER_AGGREGATOR number
does not need to fit into only the first level interrupt
bits. Before the extension of the interrupt bit masks if
the MAX_IRQ_PER_AGGREGATOR bits was larger than the first
level of interrupts then the first level bits could overflow
into the second level. This is no longer necessary to check
since the user can set the correct number of bits needed per
level.
