clk: mux: remove redundant initialization of variable width

Browse Source 
Variable width is being ininitialized with a value that is never read.
The ininitializtion is redundant and can be removed. Move the variable
to the scope it is required.

Cleans up cppcheck warning:
Variable 'width' is assigned a value that is never used.
