media: rcar-vin: fix redeclaration of symbol

[ Upstream commit 4e673ed4e2bfac00b3c3043a84e007874c17c84d ]

When adding support for parallel subdev for Gen3 it was missed that the
symbol 'i' in rvin_group_link_notify() was already declared, remove the
dupe as it's only used as a loop variable this have no functional
change. This fixes warning:

    rcar-core.c:117:52: originally declared here
    rcar-core.c:173:30: warning: symbol 'i' shadows an earlier one

Fixes: 1284605dc821cebd ("media: rcar-vin: Handle parallel subdev in link_notify")
