Konstantin Belousov eac91e326a Reduce the amount of calls to VOP_BMAP() made from the local vnode 
pager.  It is enough to execute VOP_BMAP() once to obtain both the
disk block address for the requested page, and the before/after limits
for the contiguous run.  The clipping of the vm_page_t array passed to
the vnode_pager_generic_getpages() and the disk address for the first
page in the clipped array can be deduced from the call results.

While there, remove some noise (like if (1) {...}) and adjust nearby
code.
