uses this length in the munmap call. This can lead to unmapping an extra

To prevent this from happening, the munmap call now uses the same length
that was passed to mmap. This could also have been fixed by not changing

console: unify fgetc function when console MUX is deactivated
Unify the fgetc function when MUX is activated or not:
- always call tstc() : it is the normal behavior expected
by serial uclass (call tstc then getc) and that avoids
issue when SERIAL_RX_BUFFER is activated
- reload WATCHDOG in the char waiting loop
This patch allow to have the same behavior when CONSOLE_MUX is activated
or not and avoid regression when this feature is deactivated.

is not called.
