[Qemu-devel] [PATCH] tcg/aarch64: Fix tcg_out_qemu_{ld, st} for linux-user

["Andreas Färber" <afaerber@suse.de>]

The argument order for the !CONFIG_SOFTMMU case was jumbled up since
ffc6372851d8631a9f9fa56ec613b3244dc635b9 ("tcg/aarch64: use 32-bit
offset for 32-bit user-mode emulation"), regressing from -rc2 to v2.4.0.
Fix their order to avoid segfaults, e.g., in openSUSE's GNU coreutils 8.24.
