HID: lenovo: silence unreachable code warning

In theory, this code used to return 0 if CONFIG_ACPI_PLATFORM_PROFILE was
disabled.  It's not clear if that was a config which would actually boot
so we've removed the CONFIG_ACPI_PLATFORM_PROFILE ifdef.  But now the
"return 0;" statement is unreachable and static checker tools complain.

Delete it and pull the else statement in a tab to silence the checker
warning and make the code a bit more clear.
