genirq: No need to mask non trigger mode flags before __irq_set_trigger()
Some callers of __irq_set_trigger() masks all flags except trigger mode
flags. This is unnecessary, ase __irq_set_trigger() already does this
before usage of flags.
[ tglx: Moved the flag mask and adjusted comment. Removed the hunk in
enable_percpu_irq() as it is required there ]
