x86/fsgsbase/64: Use TASK_SIZE_MAX for FSBASE/GSBASE upper limits
The GSBASE upper limit exists to prevent user code from confusing
the paranoid idtentry path. The FSBASE upper limit is just for
consistency. There's no need to enforce a smaller limit for 32-bit
tasks.
Just use TASK_SIZE_MAX. This simplifies the logic and will save a
few bytes of code.
