target-mips: fix user-mode emulation startup
Running programs with the MIPS user-mode emulator fails during dynamic
loading, as floating-point instructions are not enabled in in
env->hflags. Move the code for doing so from fpu_init to cpu_reset so
the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset
setting env->hflags to MIPS_HFLAG_UM.
The same end can be achieved by swapping the ordering of fpu_init and
cpu_reset in cpu_mips_init, but it seemed better to consolidate the
CONFIG_USER_ONLY code into a single location.
