qlcnic: Fix CPU soft lockup while collecting firmware dump
[ Upstream commit 22e984493a41bf8081f13d9ed84def3ca8cfd427 ]
Driver while collecting firmware dump takes longer time to
collect/process some of the firmware dump entries/memories.
Bigger capture masks makes it worse as it results in larger
amount of data being collected and results in CPU soft lockup.
Place cond_resched() in some of the driver flows that are
expectedly time consuming to relinquish the CPU to avoid CPU
soft lockup panic.
