Zhipeng Lu 56dc4afb9f atm: idt77252: fix a memleak in open_card_ubr0
[ Upstream commit f3616173bf9be9bf39d131b120d6eea4e6324cb5 ]

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.
