setup_current_filesystem: fail if name_max is 0

Add error handling to the USE_READDIR_R code paths that set name_max
from struct statfs or statvfs; if the determined name_max == 0
then return an error.

Avoids a crash in tree_dir_next_posix() when the calculation of
dirent_size from name_max is too small for the memory allocated
for struct dirent.

This may fix Github issue #1149
This may fix NetBSD PR https://gnats.netbsd.org/56080
