[PATCH 15/18] xfs_repair: fix 'bno' shadow vars in scan.c

[Eric Sandeen <sandeen@redhat.com>]

scan.c has 3 functions which accept 'bno' as an argument, but then use a
local variable of the same name for a different purpose in an inner scope,
which causes sparse warnings.
Rename these inner-scope loop variables 'agbno' to fix this.
