[PATCH 13/13] platform/x86: hp-bioscfg: advance elem past consumed array elements in passwdobj-attributes

[Muhammad Bilal <meatuni001@gmail.com>]

Same defect as the companion fix to enum-attributes.c in this series,
present here in both the PREREQUISITES and PSWD_ENCODINGS cases: each
consumes "size" consecutive ACPI package elements, but the outer loop
only advances "elem" by one per iteration, causing the next iteration
to misread a leftover entry as the next property and abort the parse
with -EIO on the resulting type mismatch.

Fix by advancing "elem" by (size - 1) after each of the two loops.
