When using iface, bnx2i was unable to offload further connections after all
active sessions are logged out. bnx2i will unregister the device from cnic
when the last connection is torn down. Next call to ep_connect() will fail
because the device is not registered. This issue is not seen if shost == NULL
is passed to ep_connect() call because in that case bnx2i will registers all
known devices with cnic before doing a route look-up. When shost != NULL,
bnx2i knows the device on which to offload the connection and has to register
this device before attempting to offload the connection

convert bnx2i_dev_lock to type mutex from rwlock_t because
cnic->register_device() can sleep for various reasons including memory
allocation, waiting for ISCSI_INIT completion and while acquiring mutex lock,
cnic_lock.

Fixed bnx2i_init_one() to properly handle return code of
cnic->register_device() and propagate it back to the caller. No need to check
for BNX2I_CNIC_REGISTERED, because unless the adapter is added to adapter_list
it will not be registered in ep_connect context

Removed bnx2i_reg_devices as this counter is not really
used in a meaningful way
