[PATCH 05/15] ACPICA: debugger: dbconvert: free pld_info on error return path

[Lv Zheng <lv.zheng@intel.com>]

From: Colin Ian King <colin.king@canonical.com>

ACPICA commit 23e644670539e23818fa81e2af5e89ad6657e75c

A failed allocation of new_buffer causes a leak of pld_info
because the error return path fails to free pld_info. Ensure
it is freed on the error exit path.
