[U-Boot] [PATCH] command, log: print with "log show" a full logbuffer

[Heiko Schocher]

If the logbuffer contains LOGBUFF_LEN chars, they never got
printed with the "log show" command, because chars get
printed with the following for loop:

for (i = 0; i < (size & LOGBUFF_MASK); i++) {

with size = LOGBUFF_LEN and LOGBUFF_MASK = (LOGBUFF_LEN-1)
for loop never executed ...

Fix this.
