Subject: [PATCH] soc: qcom: smem: use correct format characters

When compiling with -Wformat, clang emits the following warnings:

drivers/soc/qcom/smem.c:847:41: warning: format specifies type 'unsigned
short' but the argument has type 'unsigned int' [-Wformat]
                        dev_err(smem->dev, "bad host %hu\n", remote_host);

                             ~~~    ^~~~~~~~~~~

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
