Subject: scsi: fusion: fix string overflow warning

gcc points out a theorerical string overflow:

drivers/message/fusion/mptbase.c: In function 'mpt_detach':
drivers/message/fusion/mptbase.c:2103:17: error: '%s' directive writing up to 31 bytes into a region of size 28 [-Werror=format-overflow=]
sprintf(pname, MPT_PROCFS_MPTBASEDIR "/%s/summary", ioc->name);
               ^~~~~
drivers/message/fusion/mptbase.c:2103:2: note: 'sprintf' output between 13 and 44 bytes into a destination of size 32

We can simply double the size of the local buffer here to be on the
safe side.
