IB/mad: Fix an array index check
commit 2fe2f378dd45847d2643638c07a7658822087836 upstream.
The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS
(80) elements. Hence compare the array index with that value instead
of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity
reports the following:
Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).
Fixes: commit b7ab0b19a85f ("IB/mad: Verify mgmt class in received MADs")
