[PATCH] ide: Fix crash on repeated reset
Michal Miroslaw reported a problem (bugzilla #7023) where a user initiated
reset while the IDE layer was already resetting the channel caused a crash,
and provided a rough fix.
This is a slightly cleaner version of the fix which tracks the reset state
and blocks further reset requests while a reset is in progress.
Note this is not a security issue - random end users can't access the
ioctl in question anyway.
