[PATCH v2] net/idpf: cancel alarm when fail to init adapter

[beilei.xing at intel.com]

From: Beilei Xing <beilei.xing at intel.com>

Cancel alarm if failing to allocate vports memory during adapter_ext
initialization. Otherwise, there'll be segmentation fault when fail
to initialize adapter_ext.

Fixes: b2f9d4788d5c ("common/idpf: introduce adapter init/deinit")
