mtd: mtd_intel_dg: reset poll counter for each erase

Browse Source 
The non-posted erase polling counter is initialized only once per MTD
erase request. Large requests therefore share the polling budget across
all 4K erase commands and can fail with -ETIME even though no individual
command timed out.

Reset the counter for each 4K erase command so every operation gets the
intended completion timeout.
