ACPICA: Parser: Fix a regression in LoadTable support
ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29 LoadTable allows an alternative RootPathString than the default "\", while the new table execution support fails to keep this logic. This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this regression. Linux upstream is not affected by this regression as we haven't enabled the new table execution support there. BZ 1326, Lv Zheng.
