ACPI: sysfs: Finish sysfs init when creating a table file fails

Browse Source 
If creating the file for a table fails, acpi_tables_sysfs_init()
returns without sending the uevents for the tables directories, and
acpi_sysfs_init() returns before creating the hotplug and pm_profile
files.

Stop creating table files at that point, but finish the rest of the
initialization. Skipping only the failed table would give its file
name to the next table with the same signature, so reading that file
would return the failed table.
