[openib-general] [PATCH] fix CA type name truncation

[Tom Duffy]

Increase the size of ca_type to accommodate string printed out of ARBEL
in TAVOR compat mode.

Before:
[root at flopteron2 bin]# ./ibstat
CA 'mthca0':
        CA type: MT25208 (MT23108 coma0
<snip>

After:
[root at flopteron2 bin]# ./ibstat
CA 'mthca0':
        CA type: MT25208 (MT23108 compat mode)
<snip>

Note: there is still a bug (probably in sys_read_string()) that does not
zero out the last character, thus the a0 is printed (which is the next
string in the struct).
