[PATCH v4 1/5] misc: fs_loader: fix ubifs not unmounted on dev_get_priv error

[Christian Marangi <ansuelsmth@gmail.com>]

When dev_get_priv errors out, the ubifs is not umounted (if used).

Correctly handle this handle condition and while at it also return -EINVAL
instead of -ENOMEM as a better error since no memory is allocated but is
actually an invalid scenario for fw_get_filesystem_firmware().
