There are two places where pointer p is being assigned a value that
is never read, the pointer is re-assingned later. The assignments
are redundant and can be removed.
Cleans up two clang scan build warnings:
drivers/soc/fsl/dpio/qbman-portal.c:662:3: warning: Value stored to 'p'
is never read [deadcode.DeadStores]
drivers/soc/fsl/dpio/qbman-portal.c:820:3: warning: Value stored to 'p'
is never read [deadcode.DeadStores]
