valid_extensions (the number of EDID extensions found to be valid)
can never be > block[EDID_EXTENSION_FLAG_OFFSET].
There is no point of reallocating the block in this case: the
extra blocks at the end of the EDID structure will not hurt,
also the implementation of krealloc() will just return the same
block.
