net: mvpp2: Fix parser entry init boundary check 

Boundary check in mvpp2_prs_init_from_hw must be done according to the
passed "tid" parameter, not the mvpp2_prs_entry index, which is not yet
initialized at the time of the check.

Fixes: 47e0e14eb1 ("net: mvpp2: Make mvpp2_prs_hw_read a parser entry init function")
