The assignments to sect and off use the pointer from ctxt.cur_dev but
that has not been NULL checked before this is done. So instead move the
assignments after the NULL check.

fs/erofs: fix an integer overflow in symlink resolution2025-02-18T18:32:07ZGao Xianghsiangkao@linux.alibaba.com2025-02-13T11:28:47Zurn:sha1:7a45cb4ffeff034304789954bb222ddd7d02104a
See the original report [1], otherwise len + 1 will be overflowed.
Note that EROFS archive can record arbitary symlink sizes in principle,
so we don't assume a short number like 4096.
