soc: qcom: smem: a few last cleanups
This patch contains several small cleanups:
- In qcom_smem_enumerate_partitions(), change the "local_host"
argument to have 16 bit unsigned type
- Also in qcom_smem_enumerate_partitions(), change the type of
the "host0" and "host1" local variables to be u16
- Fix error messages reporting host ids to use the right format
specifier
- Shorten the error messages as well, to fit on one line
- Add a compile-time check to ensure the local host value passed
to qcom_smem_enumerate_partitions() is in range
