platform/x86: dell-wmi-sysman: Use sysfs_emit{_at} in show functions

Browse source

Replace sprintf() with sysfs_emit() and sysfs_emit_at() in sysfs show
functions. sysfs_emit() and sysfs_emit_at() are preferred for formatting
sysfs output because they provide safer bounds checking.

In reset_bios_show(), use sysfs_emit_at() to avoid manual buffer size
accounting.
