qga: Plug unlikely memory leak in guest-set-memory-blocks

transfer_memory_block() leaks an Error object when reading file
/sys/devices/system/memory/memory<INDEX>/state fails with errno other
than ENOENT, and @sys2memblk is false, i.e. when the state file exists
but cannot be read (seems quite unlikely), and this is
guest-set-memory-blocks, not guest-get-memory-blocks.

Plug the leak.
