btrfs: remove impossible WARN_ON in btrfs_destroy_dev_replace_tgtdev()
We have a user report, that cppcheck is complaining about a possible NULL-pointer dereference in btrfs_destroy_dev_replace_tgtdev(). We're first dereferencing the 'tgtdev' variable and the later check for the validity of the pointer with a WARN_ON(!tgtdev); But all callers of btrfs_destroy_dev_replace_tgtdev() either explicitly check if 'tgtdev' is non-NULL or directly allocate 'tgtdev', so the WARN_ON() is impossible to hit. Just remove it to silence the checker's complains. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=205003 Signed-off-by:Johannes Thumshirn <jth@kernel.org> Reviewed-by:
