[SCSI] mptctl : shutup uninitialized variable warnings
drivers/message/fusion/mptctl.c: In function ‘mptctl_mpt_command’: drivers/message/fusion/mptctl.c:1764: warning: ‘bufIn.len’ may be used uninitialized in this function drivers/message/fusion/mptctl.c:1765: warning: ‘bufOut.len’ may be used uninitialized in this function come because gcc gets confused by some "goto" statements in above function. The warnings have been verified to be bogus, however, the function does initialize these later (after the offending goto's) in the function anyway. So let's move those initializations to top of function, thereby also shutting up these warnings.
