Harman Kalra e359e3b796 drivers/octeontx2: fix Coverity warnings
Addressed 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: 58f6f93c34 ("net/octeontx2: add module EEPROM dump")
Fixes: 38f566280a ("net/octeontx2: add link stats operations")
Fixes: b5dc314044 ("net/octeontx2: support base PTP")
Fixes: ba1b3b081e ("net/octeontx2: support VLAN offloads")
Fixes: 092b383418 ("net/octeontx2: add flow init and fini")
Fixes: 3da1b85b6d ("common/octeontx2: add FLR IRQ handler")
Fixes: 2548ab774f ("mempool/octeontx2: add context dump support")
Fixes: 2b71657c86 ("common/octeontx2: add mbox request and response definition")
