esp: fix section mismatch warning

From: Randy Dunlap <[email protected]>

Not critical.

WARNING: drivers/char/esp.o(.text+0x278): Section mismatch in reference from the function show_serial_version() to the variable .init.data:serial_version The function show_serial_version() references
the variable __initdata serial_version.
This is often because show_serial_version lacks a __initdata
annotation or the annotation of serial_version is wrong.

WARNING: drivers/char/esp.o(.text+0x27d): Section mismatch in reference from the function show_serial_version() to the variable .init.data:serial_name The function show_serial_version() references
the variable __initdata serial_name.
This is often because show_serial_version lacks a __initdata
annotation or the annotation of serial_name is wrong.
