Subject: [PATCH] arm64: fpsimd: Simplify uses of {set,clear}_ti_thread_flag()

Git-commit: 9cf5b54fafedbc381df77c7f8d2aab61f4900657
Patch-mainline: v4.15-rc1
References: fate#325866

The existing FPSIMD context switch code contains a couple of
instances of {set,clear}_ti_thread(task_thread_info(task)).  Since
there are thread flag manipulators that operate directly on
task_struct, this verbosity isn't strictly needed.

For consistency, this patch simplifies the affected calls.  This
should have no impact on behaviour.
