ublk: simplify ublk_ch_open and ublk_ch_release
fops->open and fops->release are always paired. Use simple atomic bit
ops ot indicate if the device is opened instead of a count that can
only be 0 and 1 and a useless cmpxchg loop in ublk_ch_release.
Also don't bother clearing file->private_data is the file is about to
be freed anyway.
