ceph: fix incorrect kmalloc size of pagevec mempool

Browse Source 
[ Upstream commit 03230edb0bd831662a7c08b6fef66b2a9a817774 ]

The kmalloc size of pagevec mempool is incorrectly calculated.
It misses the size of page pointer and only accounts the number for the array.

Fixes: a0102bda5b ("ceph: move sb->wb_pagevec_pool to be a global mempool")
