irq/work: Improve the flag definitions
IRQ_WORK_FLAGS is defined simply to 3UL. This is confusing as it says nothing about its purpose. Define IRQ_WORK_FLAGS as a bitwise OR of IRQ_WORK_PENDING and IRQ_WORK_BUSY and change its name to IRQ_WORK_CLAIMED. While we're at it: use the BIT() macro for all flags.
