Fix memory leak on nvram_open() and nvram_open_rdonly().
For nvram_open(), the 'fd' should be closed on error, and
mmap_area should be unmap when nvram magic can not be found.
For nvram_open_rdonly(), the 'file' variable should free before
return. Once nvram_find_mtd() return successfully, it will allocate
memory to save mtd device string.

Some MTD partitions with NVRAM have content starting in the middle. In
such case offset is set and nvram_header returns pointer to the middle.
It means we have to respect offset when calculating remaining space.
By the way use real MTD partition size (nvram_part_size variable) as we
may want to bump NVRAM_SPACE in the (very near) future.

We don't have broadcom-diag for months or years now and the correct
solution is to simply don't have "nvram" partition on WGT634U anyway.

Sytax of /proc/mtd is following:
dev: size erasesize name
which means that sscanf "mtd%d: %08x" reads size, not erasesize.
