linux-user/sparc: Remove unneeded checks of 'err' from sparc64_get_context()
Unlike the kernel macros, our __get_user() and __put_user() do not return a failure code. Kernel code typically has a style of err |= __get_user(...); err |= __get_user(...); and then checking err at the end. In sparc64_get_context() our version of the code dropped the accumulating into err but left the "if (err) goto do_sigsegv" checks, which will never be taken. Delete unnecessary if()s.
