target/arm/vfp_helper: Call set_fpscr_to_host before updating to FPSCR

Browse source 
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.

Backports commit 85795187f416326f87177cabc39fae1911f04c50 from qemu
