[PATCH v1 1/1] xen/arm: gic-v3: Fix wake-up loop in gicv3_enable_redist

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxx>

timeout starts as false and is only set on the timeout break, so the
loop always exits after one iteration and a stuck redistributor is
silently treated as woken. Use while ( 1 ) to match the sibling
gicv3_do_wait_for_rwp().

Fixes: bc183a0235 ("xen/arm: Add support for GIC v3")
