Move values of __fsdev_init parameters inside __fsdev_init

Function __fsdev_init is called at only single place in the whole
codebase, therefore the parameters have always the same values.
Instead of passing these values as parameters we can define them
as variables inside __fsdev_init and remove those parameters from
the signature.
