service: Remove unused class variables

Prevents some warnings from occurring.

service: Resolve cases of member field shadowing

Now all that remains is for kernel code to be 'shadow-free' and then
-Wshadow can be turned into an error.

core: Resolve misc straggler cases of variable shadowing

input_common: Release mouse buttons on out of focus

Resolves shadowing warnings that aren't in a particularly large
subsection of core. Brings us closer to turning -Wshadow into an error.

All that remains now is for cases in the kernel (left untouched for now
since a big change by bunnei is pending), and a few left over in the
service code (will be tackled next).

While we're at it, we can fix the is_initialized error code.
This fixes the crashes on Shante

hid: Fix touch not initializing properly if disabled

file_sys: Resolve cases of variable shadowing

game_list: Fix dir move up/down expand state

service: filesystem: Return proper error codes for CreateFile
