The variable possible_uV being assigned a value that is never read, the
control flow via the following goto statement takes a path where the
variable is not accessed. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
drivers/regulator/core.c:3935:3: warning: Value stored to 'possible_uV'
is never read [deadcode.DeadStores]
