[PATCH] HID: sony: fix RB3 Pro full report poke timer on 32-bit

[Sanjay Govind]

Rock Band 3 Pro instruments need a feature request before they send full
reports, and rb3_pro_instrument_raw_event() rate limits that request
with time_after(jiffies, sc->rb3_pro_poke_jiffies). sony_probe()
initialises rb3_pro_poke_jiffies to 0 so that the first navigation
report triggers the request.

jiffies starts at INITIAL_JIFFIES, which on 32-bit kernels is
-300 * HZ. time_after(jiffies, 0) is therefore false until jiffies
wraps five minutes after boot, so an instrument connected during that
time stays in navigation-only mode until then. 64-bit kernels are not
affected, as INITIAL_JIFFIES is positive there.

Initialise rb3_pro_poke_jiffies to the current jiffies instead, so the
request is sent as soon as navigation reports arrive after probe,
regardless of the jiffies value.

Notes:
    Reported by the Sashiko AI review bot as a pre-existing issue while
    reviewing "HID: sony: fix sleeping in atomic context in RB3 Pro raw
    event handler". Built with W=1 on x86_64. The 32-bit early boot case
    was found by reading include/linux/jiffies.h and was not reproduced.
    
    The fix and changelog were written with the help of an AI coding
    assistant (Claude Opus 5.5).
