[PATCH] staging: octeon: Add prevent NAPI from scheduling IN-REPLY-TO:

[Marina Makienko]

There are netif_napi_add() and napi_enable() in for_each_possible_cpu
loop in function cvm_oct_rx_initialize(). So it's logical to add
napi_disable() in for_each_possible_cpu loop in function
cvm_oct_rx_shutdown().

Found by Linux Driver Verification project (linuxtesting.org).
