mmc: remove unnecessary call to single_release

Browse Source 
PD#151361: Oops when doing OTA upgrading

    in single_release file->private_data will be dereferenced,
which is assigned a value by single_open. So if signle_open
is not called before single_release, an "unable to handle
kernel NULL pointer..." issue will appear.
    But in this case, since single_open and seq_read is not
called, there is no need calling single_release to release
mem allocated by single_open and seq_read. Simpley remove
calling single_release is the best choise
