[PATCH 2/3] mtd: rawnand: qcom: Clear buf_count and buf_start in raw read

[Md Sadre Alam]

Initialize buf_count and buf_start to 0 before starting the
raw read. If we will not initialize then read staus will get
updated with wrong value and we will see failure for even
successful raw read transaction.
