tty: vt: remove unneeded assignment of EPecma to vc_priv

vc_data::vc_priv is _always_ assigned before the ESgetpars case is
entered (in ESsquare). Therefore, there is no need to reset it when
leaving the ESgetpars case. Note the state is set to ESnormal few lines
above, so ESgetpars is entered only by the next CSI.

Therefore, this obfuscation can be removed.
