[PATCH] ubi: fastmap: clean up the initialization of pointer p

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

The pointer p is being initialized with one value and a few lines
later being set to a newer replacement value. Clean up the code by
using the latter assignment to p as the initial value. Cleans up
clang warning:

drivers/mtd/ubi/fastmap.c:217:19: warning: Value stored to 'p'
during its initialization is never read
