linux-user: Check dump_write() return in elf_core_dump()
One of the calls to dump_write() in elf_core_dump() was missing a check for failure (spotted by Coverity). Add the check to bring it into line with the other calls from this function. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
