[PATCH] Change variable name from spd to det in ahci.c, to reflect specs

[Andrea G. Monaco]

Hello,


while working on this bug
(https://mail.gnu.org/archive/html/help-hurd/2020-12/msg00003.html)
and reading the AHCI specification, I found out that a variable is named
incorrectly though used properly.
The correct name is det, while spd is another field.
Maybe it's worth correcting for consistency with the specification.


Warmly,
Andrea
