In the functions mvpp2_isr_handle_xlg() and
mvpp2_isr_handle_gmac_internal(), the bool variable link is assigned a
true value in the case that a given bit of val is set. However, if the
bit is unset, no value is assigned to link and it is then passed to
mvpp2_isr_handle_link() without being initialised. Fix by assigning to
link the value of the bit test.
Build-tested on x86.
