fix(lsp): tagfunc fails in unusual buffer #30700

Problem:
tagfunc failed in a weird buffer (either a directory or some other
non-file buffer, I don't remember):

    E987: Invalid return value from tagfunc
    E5108: Error executing lua …/runtime/lua/vim/lsp/util.lua:311: EISDIR: illegal operation on a directory
    stack traceback:

at this line:

    local data = assert(uv.fs_read(fd, stat.size, 0))

Solution:
Check for directory.
