ACPI / tables: Return proper error codes from acpi_table_parse() and fix comment.

Browse source 
The comment about return value of acpi_table_parse() is incorrect.
This patch fix it.

Since all callers only check if the function succeeded or not, this
patch simplifies the semantics by returning -errno for all failure
cases. This will also simply the comment.

As suggested by Toshi Kani <toshi.kani@hp.com>, also change the stub
in linux/acpi.h to return -ENODEV.
