ALSA: opl3: Hardening for potential Spectre v1
commit 7f054a5bee0987f1e2d4e59daea462421c76f2cb upstream.
As recently Smatch suggested, one place in OPL3 driver may expand the
array directly from the user-space value with speculation:
sound/drivers/opl3/opl3_synth.c:476 snd_opl3_set_voice() warn: potential spectre issue 'snd_opl3_regmap'
This patch puts array_index_nospec() for hardening against it.
