gcc fails to see that the use of the 'last_offset' variable
in hns_nic_reuse_page() is used correctly and issues a bogus
warning:

drivers/net/ethernet/hisilicon/hns/hns_enet.c: In function 'hns_nic_reuse_page':
drivers/net/ethernet/hisilicon/hns/hns_enet.c:541:6: warning: 'last_offset' may be used uninitialized in this function [-Wmaybe-uninitialized]

This simplifies the function to make it more obvious what is
going on to both readers and compilers, which makes the warning
go away.

Compile-tested only, and complex enough that this requires a proper
review and testing before it gets apply. Please have a look at this.

If this goes yet another day without being reviewed, I'm just applying
it.

You hisilicon folks can't just let patches rot, you must review them
in a timely manner or else I'm applying them without waiting for you
to look at them.

Hi David and Arnd,
Apologies for the delay in response and the review. Most of us were on 
the Annual Holidays and have just returned back.

Change looks good to me!

Best Regards
Salil
