wifi: rtw88: 8821a/8812a: Set ptct_efuse_size to 0

Some RTL8812AU devices fail to probe:

[   12.478774] rtw_8812au 1-1.3:1.0: failed to dump efuse logical map
[   12.487712] rtw_8812au 1-1.3:1.0: failed to setup chip efuse info
[   12.487742] rtw_8812au 1-1.3:1.0: failed to setup chip information
[   12.491077] rtw_8812au: probe of 1-1.3:1.0 failed with error -22

It turns out these chips don't need to "protect" any bytes at the end of
the efuse.

The original value of 96 was copied from rtw8821c.c.

No one reported any failures with RTL8821AU yet, but the vendor driver
uses the same efuse reading code for both chips.
