[PATCH v4 5/9] net/ixgbe/base: fix lock checker errors

[Bruce Richardson <bruce.richardson@intel.com>]

When building on FreeBSD, errors are reported in the base code by the
lock checker (-Wthread-safety). For example:

../drivers/net/intel/ixgbe/base/ixgbe_osdep.c:42:1: error: mutex 'lock->mutex' is still held at the end of function [-Werror,-Wthread-safety-analysis]
   42 | }
      | ^

These errors are due to the checker not recognising the lock wrapper
functions. We can avoid these errors by converting these functions into
macros. While converting the lock macros, we can also convert the memory
allocation functions too, which allows us to remove the osdep.c file
entirely from the build.

Fixes: 30b19d1b5c43 ("net/ixgbe/base: add definitions for E610")
