[PATCH net-next v2 1/5] mvpp2: refactor BM pool init percpu code

[Matteo Croce]

From: Matteo Croce <mcr...@microsoft.com>

In mvpp2_swf_bm_pool_init_percpu(), a reference to a struct
mvpp2_bm_pool is obtained traversing multiple structs, when a
local variable already points to the same object.

Fix it and, while at it, give the variable a meaningful name.
