[PATCH] Revert "memory-hotplug: add 0x prefix to HEX block_size_bytes"

[Heiko Carstens <heiko.carstens@de.ibm.com>]

From: Heiko Carstens <heiko.carstens@de.ibm.com>

Revert ba168fc37dea145deeb8fa9e7e71c748d2e00d74 "memory-hotplug: add 0x prefix
to HEX block_size_bytes" since it changes the user space visible sysfs interface
/sys/devices/system/memory/block_size_bytes.
The change breaks existing user space applications which rely on the fact that
the output does not contain the "0x" prefix.
