bnxt_en: Fix RCU locking for ntuple filters in bnxt_srxclsrldel()

After looking up an ntuple filter from a RCU hash list, the
rcu_read_unlock() call should be made after reading the structure,
or after determining that the filter cannot age out (by aRFS).
The existing code was calling rcu_read_unlock() too early in
bnxt_srxclsrldel().

As suggested by Simon Horman, change the code to handle the error
case of fltr_base not found in the if condition.  The code looks
cleaner this way.
