The mlx5 PMD manages the device using two modes: the Verbs API
and the DevX API. Each API offers its own method for querying
the maximum work queue size (in descriptors).
The corrected patch enhanced the rte_eth_dev_info_get() API
support in mlx5 PMD to return the true maximum number of descriptors.
It also implemented a limit check during queue creation, but this
was applied only to "DevX mode." Consequently, the "Verbs mode"
was overlooked, leading to malfunction on legacy NICs that do
not support DevX.
This patch adds support for Verbs mode, and all limit checks are
updated accordingly.
