power: supply: rt9467: Return error on failure in rt9467_set_value_from_ranges()

Browse Source 
[ Upstream commit 8b27fe2d8d ]

The return value of rt9467_set_value_from_ranges() when setting AICL VTH is
not checked, even though it may fail.

Log error and return from rt9467_run_aicl() on fail.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
