When the following formula is executed during initialization, the
private variable named hw->tqps_num has not been obtained from PF driver

On the other hand, because the private variable named hw->num_msi, which

the '.get_reg' ops implementation function to dump all interrupt related

Adding the trace module caused this issue to appear again, due to

This patch solves this issue by resetting the bool type, immediately

eal/x86: ignore gcc 10 stringop-overflow warnings

stringop-overflow warns when it sees a possible overflow
in a string operation.

In the rte_memcpy functions different branches are taken
depending on the size. stringop-overflow is raised for the
branches in the function where it sees the static size of the
src could be overflowed.

However, in reality a correct size argument and in some cases
dynamic allocation would ensure that this does not happen.

For example, in the case below for key, the correct path will be
chosen in rte_memcpy_generic at runtime based on the size argument
but as some paths in the function could lead to a cast to 32 bytes
a warning is raised.
