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

[beilei . xing]

From: Beilei Xing <beilei.x...@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: 2d823ecd671c ("net/cpfl: support device initialization")
