f2fs: fix to initialize map.m_pblk in f2fs_precache_extents()
[ Upstream commit 8b07c1fb0f1ad139373c8253f2fad8bc43fab07d ]
Otherwise, it may print random physical block address in tracepoint
of f2fs_map_blocks() as below:
f2fs_map_blocks: dev = (253,16), ino = 2297, file offset = 0, start blkaddr = 0xa356c421, len = 0x0, flags = 0
Fixes: c4020b2da4c9 ("f2fs: support F2FS_IOC_PRECACHE_EXTENTS")
