[Qemu-devel] [PATCH] target/arm/vfp_helper: Call set_fpscr_to_host before updating to FPSCR

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

In commit e9d652824b0 we extracted the vfp_set_fpscr_to_host()
function but failed at calling it in the correct place, we call
it after xregs[ARM_VFP_FPSCR] is modified.

Fix by calling this function before we update FPSCR.
