net/ethtool: drop duplicate TSCONFIG HWTSTAMP BUILD_BUG_ON from SET handler

BUILD_BUG_ON() is evaluated at compile time. The same three checks
for __HWTSTAMP_TX_CNT, __HWTSTAMP_FILTER_CNT and __HWTSTAMP_FLAG_CNT
are already present earlier in this file (tsconfig_reply_size()).
Repeating them at the start of ethnl_set_tsconfig() does not
strengthen the guarantee; remove the redundant block there and
keep a single occurrence.
