powerpc/64: Fix bug in setting floating-point exception mode
When loading up the FPU, we were using a 'ld' (load doubleword) instruction to get the FP exception mode from the thread_struct, but it's only an int field. This changes the ld to lwz (load word and zero-extend). Signed-off-by: Paul Mackerras <paulus@samba.org>
