23edc362ff compress/isal: fix log type name
There is a naming convention for logtypes of PMDs:
"pmd.driverType.driverName".
Therefore, the logtype for ISA-L PMD should be "pmd.compress.isal".

6a000343ed compress/isal: fix offset usage
This patch allows the ISA-L compression PMD,
to be used with offsets in the mbuf.
Offsets can now be used for source and destination buffers,
during compression or decompression.

2519de891e compress/qat: prevent usage if incorrect firmware
Previous check only causes op to fail on dequeue.
This extends so once first fail is detected, application can
no longer enqueue ops to the device and will also get an
appropriate error if trying to reconfigure or setup the device.
