lib/crc32: standardize on crc32c() name for Castagnoli CRC32

For historical reasons, the Castagnoli CRC32 is available under 3 names:
crc32c(), crc32c_le(), and __crc32c_le().  Most callers use crc32c().
The more verbose versions are not really warranted; there is no "_be"
version that the "_le" version needs to be differentiated from, and the
leading underscores are pointless.

Therefore, let's standardize on just crc32c().  Remove the other two
names, and update callers accordingly.

Specifically, the new crc32c() comes from what was previously
__crc32c_le(), so compared to the old crc32c() it now takes a size_t
length rather than unsigned int, and it's now in linux/crc32.h instead
of just linux/crc32c.h (which includes linux/crc32.h).

Later patches will also rename __crc32c_le_combine(), crc32c_le_base(),
and crc32c_le_arch().
