There is no point in calling 'free_irq()' explicitly for
'WCD9335_IRQ_SLIMBUS' in the remove function.

The irqs are requested in 'wcd9335_setup_irqs()' using a resource managed
function (i.e. 'devm_request_threaded_irq()').
'wcd9335_setup_irqs()' requests all what is defined in the 'wcd9335_irqs'
structure.
This structure has only one entry for 'WCD9335_IRQ_SLIMBUS'.

So 'devm_request...irq()' + explicit 'free_irq()' would lead to a double
free.

Remove the unneeded 'free_irq()' from the remove function.
