Kernel: Use try_create not must_create in SysFSUSB::create

Browse source 
The function `KString::must_create()` can only be enforced
during early boot (that is, when `g_in_early_boot` is true), hence
the use of this function during runtime causes a `VERIFY` to assert,
leading to a Kernel Panic.
We should instead use `TRY()` along with `try_create()` to prevent
this from crashing whenever a USB device is inserted into the system,
and we don't have enough memory to allocate the device's KString.
