[PATCH v2] nvdimm/btt: fix sequence endian in btt_log_read error print

[Ben Dooks <ben.dooks@codethink.co.uk>]

The error reporting in btt_log_read() prints sequence numbers out
from the log which are stored in little endian without any endian
conversion. Make sure these are passed throuhg endian convesion
before going to the kernel console so the user sees the correct
sequence number and to avoid any warnings from sparse due to
endian conversion.

Fix the following (prototype) sparse warnings:
drivers/nvdimm/btt.c:342:17: warning: incorrect type in argument 5 (different base types)
drivers/nvdimm/btt.c:342:17:    expected int
drivers/nvdimm/btt.c:342:17:    got restricted __le32 [usertype] seq
drivers/nvdimm/btt.c:342:17: warning: incorrect type in argument 6 (different base types)
drivers/nvdimm/btt.c:342:17:    expected int
drivers/nvdimm/btt.c:342:17:    got restricted __le32 [usertype] seq
