[PATCH linux-next] octeontx2-af: Remove redundant assignment operations

[luo penghao]

From: penghao luo <luo.penghao@xxxxxxxxxx>

the variable err will be reassigned on subsequent branches, and this
assignment does not perform related value operations.

clang_analyzer complains as follows:

drivers/net/ethernet/marvell/sky2.c:4988: warning:

Although the value stored to 'err' is used in the enclosing expression,
the value is never actually read from 'err'.
