[resend PATCH] kernelbase: Get language sort only when required in LCMapStringEx().

[Paul Gofman]

Fixes very slow loading (a few minutes) of Warhammer 40000: Inquisitor - Martyr
after b780e5f5b1bd018629bfa31431e216c7579fe9aa.

    The 'todo_wine' test in kernel32/tests/locale.c shows that LCMapStringEx should fail for
    invalid locale but this should happen regardless of LCMAP_LINGUISTIC_CASING flag
    and should probably be checked separately.
