spi/flashconsole: Fix internal buffer overflow
Once the console's FMAP region is full, we stop clearing the line
buffer and `line_offset` is not reset anymore. Hence, sanity check
`line_offset` everytime before writing to the buffer.
The issue resulted in boot hangs and potentially a brick if the
log was very verbose.
