drivers: thermal: intel: tcc_cooling: Drop redundant local variable

Simplify the error path by directly returning PTR_ERR(tcc_cdev)
instead of storing it in an intermediate variable ret which can be
dropped then because it is only used for that.

Also remove an uneeded empty line before the declaration of local
variable err.
