iwlwifi: speed up event log dumps
Take advantage of device's auto-increment for SRAM reads to eliminate extra
write address accesses.
Grab/release NIC access before/after entire read sequence, rather than for
each read individually.
After a quick check of dmesg logs, this seems to double Event Log dump speed,
reducing from about 20 milliseconds to about 10 milliseconds for 512 entries
using 3945.
