Addresed issues reported by coverity: NULL pointer dereferencing
issues, unchecked return value, uinitialized scalar value,
probable deadcode cases, unintended sign extension, bad bit
shift operation, Wrong sizeof argument (SIZEOF_MISMATCH)
Coverity issue: 343396, 345028, 344977, 345015, 345025, 344969,
Coverity issue: 345014, 344966, 343437, 344993, 345007, 344988,
Coverity issue: 343405, 344999, 345003
Fixes: 58f6f93c34c1 ("net/octeontx2: add module EEPROM dump")
Fixes: 38f566280abb ("net/octeontx2: add link stats operations")
Fixes: b5dc3140448e ("net/octeontx2: support base PTP")
Fixes: ba1b3b081edf ("net/octeontx2: support VLAN offloads")
Fixes: 092b38341859 ("net/octeontx2: add flow init and fini")
Fixes: 3da1b85b6d06 ("common/octeontx2: add FLR IRQ handler")
Fixes: 2548ab774f92 ("mempool/octeontx2: add context dump support")
Fixes: 2b71657c8660 ("common/octeontx2: add mbox request and response definition")
