atm: idt77252: fix a memleak in open_card_ubr0
[ Upstream commit f361617 ] When alloc_scq fails, card->vcs[0] (i.e. vc) should be freed. Otherwise, in the following call chain: idt77252_init_one |-> idt77252_dev_open |-> open_card_ubr0 |-> alloc_scq [failed] |-> deinit_card |-> vfree(card->vcs); card->vcs is freed and card->vcs[0] is leaked.
