ShellPkg: BcfgDisplayDump(): fix reporting of OptionalData
In this cleaned up form of BcfgDisplayDump(), it is easier to see that the
OptionalDataOffset <= BufferSize
expression, used to report whether optional data are *absent*, is
incorrect. For any well-formed EFI_LOAD_OPTION, this inequality always
holds.
Optional data are present exactly if
OptionalDataOffset < BufferSize
therefore the absence condition is the negation of the above,
OptionalDataOffset >= BufferSize
This patch fixes the bug where BCFG always reports "Optional- N", even if
optional data exist.
