e2p: Fix 's' handling in parse_num_blocks2()

parse_num_blocks2() wrongly did:
	num << 1;
when log_block_size < 0. That is obviously wrong as such statement has
no effect (and the compiler properly warns about it). Callers expect
returned value to be in bytes when log_block_size < 0 so fix the
statement accordingly.
