mm-video: venc: Correct a typo in variable name

A kernel variable was to be defined as unsigned long but
it is mistakenly defined as unsigned only, the space is
missing after long. This bug is silent because unsigned
is also a valid data type by itself.
Corresponding to kernel fix, similar correction is done
in userspace code.
