octeontx2-af: fix NULL deref in NIX TM tree debugfs read path

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-af: fix NULL deref in NIX TM tree debugfs read path

rvu_dbg_nix_tm_tree_display() dereferences pfvf->sq_ctx without
checking whether the SQ context has been allocated. Reading
/sys/kernel/debug/octeontx2/nix/tm_tree for a NIX LF whose transmit
queues are not set up triggers a kernel oops.

Guard the read path the same way rvu_dbg_nix_tm_tree_write() already
does and return -EINVAL with a seq_file message when sq_ctx is NULL.
