Restore NtCreateX case handling with FILE_FLAG_POSIX_SEMANTICS to the way

Browse Source 
it worked in 3.3.x and 3.2.x. UCF_POSIX_PATHNAMES may no longer be needed,
as lp_posix_pathnames() being set isn't the same as case handling from
NtCreateX (lp_posix_pathnames() changes the STAT calls to LSTAT, not
the case semantics).
