mpssd: fix buffer overflow warning
The compilation emits a warning in function ‘snprintf’,
inlined from ‘set_cmdline’ at
../Documentation/mic/mpssd/mpssd.c:1541:9:
/usr/include/x86_64-linux-gnu/bits/stdio2.h:64:10:
warning: call to __builtin___snprintf_chk will always overflow
destination buffer
This was introduced in commit f4a66c204482 ("misc: mic: Update MIC host
daemon with COSM changes") and is fixed by reverting the changes to the
size argument of these snprintf statements.
