ACPICA: Remove spurious precision from format used to dump parse trees

The debug code in acpi_ps_delete_parse_tree() uses ("%*.s", level * 4, " ")
to indent traces.

POSIX requires the empty precision be treated as zero, but the kernel treats
is as 'no precision specified'.

Change to ("%*s", level * 4, "") since there is additional whitespace and no
reason to indent by one space when level is zero.
