Ruiyu Ni fc41b97f12 ShellPkg/LoadPciRom: Fix the ConnectAll() implementation 
Old implementation depends on UefiHandleParsingLib and uses
incorrect Index to get handle type.
The simplest ConnectAll() implementation can be just to
locate all handles and call BS.ConnectController() for each
of them recursively. BS.ConnectController() does nothing
to the image handle. Such implementation is borrowed from
BDS core implementation.
