Subject: [PATCH] affs: fix shadowed variable sparse warnings

Introduce _tmp in the small if-blocks where this is shadowed.
fs/affs/file.c:573:8: warning: symbol 'tmp' shadows an earlier one
fs/affs/file.c:530:6: originally declared here
fs/affs/file.c:714:9: warning: symbol 'tmp' shadows an earlier one
fs/affs/file.c:661:6: originally declared here
fs/affs/file.c:746:9: warning: symbol 'tmp' shadows an earlier one
fs/affs/file.c:661:6: originally declared here

Remove declaration and assign to original variable as we are going
to return from the function at this point anyway.
fs/affs/file.c:831:7: warning: symbol 'size' shadows an earlier one
fs/affs/file.c:813:6: originally declared here
