[Qemu-devel] [PULL 13/26] linux-user: Check dump_write() return in elf_core_dump()

[riku . voipio]

From: Peter Maydell <peter.mayd...@linaro.org>

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.
