[PULL 09/17] hw/i386/pc: fix code comment on cumulative flash size

[Michael Tokarev]

From: Laszlo Ersek <lersek@redhat.com>

- The comment is incorrectly indented / formatted.

- The comment states a 8MB limit, even though the code enforces a 16MB
  limit.

Both of these warts come from commit 0657c657eb37 ("hw/i386/pc: add max
combined fw size as machine configuration option", 2020-12-09); clean them
up.

Arguably, it's also better to be consistent with the binary units (such as
"MiB") that QEMU uses nowadays.
