esp: fix section mismatch warning

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.
