ShellPkg/CommandLib: avoid NULL derefence and memory leak
Since TianoCore EDK2 commit d65f2cea36d1 ("ShellPkg/CommandLib: Locate
proper UnicodeCollation instance") in edk2 the UEFI Shell crashes if EFI
variable PlatformLang is not defined due to dereferencing gUnicodeCollation
gUnicodeCollation (= NULL) in ShellCommandRegisterCommandName().
Furthermore CommandInit() is leaking PlatformLang if
gUnicodeCollation != NULL.
Close the memory leak and use the first UnicodeCollation instance if
PlatfomLang is not defined.
Fixes: d65f2cea36d1 ("ShellPkg/CommandLib: Locate proper UnicodeCollation
instance")
