ACPICA: Fix for some local named nodes not marked temporary and to disallow duplicates
Fixed a problem with the CreateField, CreateXXXField (Bit, Byte,
Word, Dword, Qword), Field, BankField, and IndexField operators
when invoked from inside an executing control method. In this case,
these operators created namespace nodes that were incorrectly
left marked as permanent nodes instead of temporary nodes. This
could cause a problem if there is race condition between an
exiting control method and a running namespace walk. (Reported
by Linn Crosetto). Fixed a problem where the CreateField and
CreateXXXField operators would incorrectly allow duplicate names
(the name of the field) with no exception generated.
