ShellPkg: UefiHandleParsingLib: remove tautological comparison

The code being removed in this patch dates back to git commit a405b86d274d
(Sep 14, 2010; "udk2010.up2.shell initial release."). The condition always
evaluates to true, and it breaks DEBUG builds of ArmVirtPkg with gcc-6.1:

  ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c:
    In function 'ParseHandleDatabaseByRelationshipWithType':
  ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.c:2465:76:
    error: self-comparison always evaluates to true
    [-Werror=tautological-compare]
         ASSERT((*HandleType)[HandleIndex] == (*HandleType)[HandleIndex]);
