fsck.c: refactor fsck_msg_type() to limit scope of "int msg_type"

Refactor "if options->msg_type" and other code added in
0282f4dced0 (fsck: offer a function to demote fsck errors to warnings,
2015-06-22) to reduce the scope of the "int msg_type" variable.

This is in preparation for changing its type in a subsequent commit,
only using it in the "!options->msg_type" scope makes that change

This also brings the code in line with the fsck_set_msg_type()
function (also added in 0282f4dced0), which does a similar check for
"!options->msg_type". Another minor benefit is getting rid of the
style violation of not having braces for the body of the "if".
