[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.
