Subject: [PATCH] gainfar.c : code cleanup

This patch relates to "[PATCH] gainfar.c : skb_over_panic 
(kernel-2.6.32.15)"

While in 2.6.32.15 it actually fixed a bug here it merely cleans up the 
previous attempts to fix the bug with a more coherent code.

Currently before queuing skb into the rx_recycle it is 
"un-skb_reserve"-ed so when taken out in gfar_new_skb() it wont be 
reserved twice.

This patch makes sure the alignment skb_reserve is done once, upon 
allocating the skb and
not when taken out of the rx_recycle pool. Eliminating the need to undo 
anything before queue skb back to the pool.

NOTE: This patch will compile and is fairly straight forward  but I do 
not have environment to test it as I did with the 2.6.32.15 fix.
