[PATCH] wifi: mt76: use hrtimer_setup() in mt76x02u beacon init

[Mieczyslaw Nalewaj <namiltd@yahoo.com>]

Replace the two-step hrtimer initialization pattern with a single
consolidated call to hrtimer_setup().
The legacy approach of calling hrtimer_init() followed by manual
assignment to timer.function is deprecated. The new hrtimer_setup()
helper atomically initializes the timer and assigns the callback
function in one operation, eliminating the race-prone intermediate
state where the timer is initialized but lacks a handler.
