Subject: [PATCH] mei: bus: Add newline to sysfs attribute outputs

Append newline characters to sysfs_emit() outputs in func max_conn_show(),
fixed_show(), and vtag_show(). This aligns with common kernel conventions
and improves readability for userspace tools that expect
newline-terminated values.
