[PATCH] staging: nvec: nvec_power: use GFP_KERNEL in probe()

[Igor Putko]

nvec_power_probe() calls devm_kzalloc() with GFP_NOWAIT, which
disables direct reclaim and is meant for atomic context. probe()
runs in normal process context and may sleep, so this needlessly
risks a spurious -ENOMEM under memory pressure instead of just
waiting for reclaim like every other probe() allocation does.

nvec.c's own tegra_nvec_probe() already uses GFP_KERNEL for the
identical pattern, confirming this is an oversight, not intentional.
