Input: bma150 - fix checking pm_runtime_get_sync() return value

When PM_RUNTIME is not defined, pm_runtime_get_sync() returns 1, see
include/linux/pm_runtime.c::__pm_runtime_resume(), and the check of the
return value was overlooking this, in this case bma150_open() would
return 1 which is not expected by upper layers.

Maybe the check for != -ENOSYS (Function not implemented) was meant to
cover this, but pm_runtime_get_sync() does not return this value.

For now fix the issue locally by checking explicitly for negative return
values.
