net: tftp: Fix store_block offset calculation

tftp_cur_block start with 1 for first block, but tftp_cur_block counter is
start with zero when block number is rollover. The existing code
"tftp_cur_block - 1" will cause the block number become -1 in store_block()
when tftp_cur_block is 0 when tftp_cur_block is rollover.

The fix pass in tftp_cur_block to store_block() and minus the
tftp_block_size when do the offset calculation.
