----------------------------------------------------------------------

The specified buffer length for three debugfs files fd_tcam, uc and tqp
is not enough for their maximum needs, so this patch fixes them.

Fixes: b5a0b70d ("net: hns3: refactor dump fd tcam of debugfs")
Fixes: 1556ea91 ("net: hns3: refactor dump mac list of debugfs")
Fixes: d96b0e59 ("net: hns3: refactor dump reg of debugfs")
