[PATCH] nfc: virtual_ncidev: change default device permissions

[Thadeu Lima de Souza Cascardo]

Device permissions is S_IALLUGO, with many unnecessary bits. Remove them
and also remove read and write permissions from group and others.

Before the change:
crwsrwsrwt    1 0        0          10, 125 Nov 25 13:59 /dev/virtual_nci

After the change:
crw-------    1 0        0          10, 125 Nov 25 14:05 /dev/virtual_nci
