LoongArch: Use more appropriate assertions for the relocation of TLS LE

PR ld/33427

    c: Update TLS model after processing a TLS variable

    Set a tentative TLS model in grokvardecl and update TLS mode with
    the default TLS access model after a TLS variable has been fully
    processed if the default TLS access model is stronger,

triggered a linker error when building glibc using build-many-glibcs.py.

See: https://sourceware.org/pipermail/binutils/2025-September/144225.html

This fix uses more appropriate assertions.
