memfd: fix possible usage of the uninitialized file descriptor
The qemu_memfd_alloc_check() routine allocates the fd variable on stack.
This variable is initialized inside the qemu_memfd_alloc() function.
There are several cases when *fd will be left unintialized which can
lead to the unexpected close() in the qemu_memfd_free() call.
Set file descriptor to -1 before calling the qemu_memfd_alloc routine.
