Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be made the default to not leak file descriptor across exec(). In a further patch, get_unused_fd() will be removed so that new code start using get_unused_fd_flags() (or anon_inode_getfd()) with correct flags. This patch replaces calls to get_unused_fd() with equivalent call to get_unused_fd_flags(0).
