linux-user/signal.c: Remove only-ever-set variable fpu_save_addr
Move the access of fpu_save into the commented out skeleton code for
restoring FPU registers on SPARC sigreturn, thus silencing a gcc
4.6 "variable set but never used" warning.
(This doesn't affect the calculation of 'err' because in fact
__get_user() can never fail.)
