[Angel Pons (Code Review)]

Hello build bot (Jenkins), Nico Huber,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: it87spi.c: Prevent use-after-free bug

it87spi.c: Prevent use-after-free bug

The memory for the `param` string is aliased by `dualbiosindex_suffix`.
Moreover, `errno` could have been modified by the call to `free()`.
Therefore, only free the former when there are no more uses of either.
