drivers/platform/mellanox: Convert snprintf to sysfs_emit

JIRA: https://issues.redhat.com/browse/RHEL-45234

commit e5afa3d
Author: Li Zhijian <lizhijian@fujitsu.com>
Date: Tue, 16 Jan 2024 12:51:23 +0800

    Per filesystems/sysfs.rst, show() should only use sysfs_emit()
    or sysfs_emit_at() when formatting the value to be returned to user space.

    coccinelle complains that there are still a couple of functions that use
    snprintf(). Convert them to sysfs_emit().

    No functional change intended
