    efivarfs: Replace invalid slashes with exclamation marks in dentries.

    Without this patch efivarfs_alloc_dentry creates dentries with slashes in
    their name if the respective EFI variable has slashes in its name. This in
    turn causes EIO on getdents64, which prevents a complete directory listing
    of /sys/firmware/efi/efivars/.

    This patch replaces the invalid shlashes with exclamation marks like
    kobject_set_name_vargs does for /sys/firmware/efi/vars/ to have consistently
    named dentries under /sys/firmware/efi/vars/ and /sys/firmware/efi/efivars/.
