Subject: [PATCH] Input: spear-keyboard - Simplify resource management

Since the commit in the Fixes tag below, 'kbd->input' is a managed resource
that doesn't need to be explicitly unregistered or freed (see
devm_input_allocate_device() documentation)

So, remove a unless line of code to slightly simplify it.

Fixes: 6102752eb354 ("Input: spear-keyboard - switch to using managed resources")
