Fix string may be truncated issue with using snprintf

Browse Source 
New compiler options introduced by commit
519c4285cf will cause DM compile failure
which caused by warnings from some snprintf usage might be truncated.

Expanding the string buffer to make compiler happy.

v3: change format string
v2: Address comment from Hao, shrink bident string size to satify
tname length in blockif_open.
