... in function grub_util_fd_open() when creation of an I/O request or
opening a device fails. The "ret", the file descriptor, will be freed
before its associated MsgPort is deleted resulting in a use-after-free
condition.
Fix this issue by freeing "ret" after its associated MsgPort has been
deleted.

During command registration, grub_register_command_prio() returns
a 0 when there is a failure in memory allocation. In such a situation,
calls to grub_unregister_{command(), extcmd()} during command
unregistration will result in dereferencing a NULL pointer.
Perform explicit NULL check in both unregister helpers to prevent
undefined behaviour due to a NULL pointer dereference.
