drivers: w1: style corrections-pointers-blanklines-comparisons

Correct pointer notations to include whitespace between
variable type and "*" character. Inserted blank line
after variable declatations at two locations.
Rearranged comparison within an if statment to have the
constant on the right-hand side.
